AB  - In the last few decades, the technology of 3D concrete printing (3DCP) has had a significant
development. This technology has a great potential to improve efficiency in the construction
industry. It can provide safer site working conditions, material savings, a reduction of
construction time, and a high versatility of architectural and structural design. However, this new
technology is still not fully investigated. The wider application is limited by the lack of standards
and guidelines for design and production.
The literature review showed that, there are only a few studies investigating structural behaviour
of 3DCP structures and elements. Beams and walls with and without addition of fibers,
reinforcement or cables under ultimate loads were tested. The incorporation of reinforcement in
the printing process, connections between printed pieces and long-term behaviour of 3DCP
elements under sustained load are opened questions.
The topic of this research was an experimental testing of 3DCP truss girder. Printing of truss
girder was done using a commercial, ready-to-use premix Sikacrete® 751 3D. In order to print,
the printer head was moved in the Z direction to alternately place two desired path layers. A truss
girder with dimensions of 87x29x12 cm, without reinforcement, was subjected to a four-point
bending test up to failure. During this testing strains in two diagonals, deflection of the two
bottom joints, and ultimate force were measured. Ultimate force was 30 kN and the brittle failure
of tensioned bottom chord occurred. The force in tensioned diagonal was 13.45 kN and in the
compressed one 36.77 kN. Additionally, three samples obtained from the top and bottom chords
were tested on axial tension. The tension capacity of samples was 25.12 kN.

AB  - The Random Forest (RF) and K nearest neighbors (KNN) machine learning (ML) algorithms were evaluated for their ability to predict ophiolite occurrences, in the East Vardar Zone (EVZ) of central North Macedonia. A predictive map of the investigated area was created using three data sources: geophysical data (digital elevation model, gravity and geomagnetic), multispectral optical satellite images (Landsat 7 ETM + and their derivatives), and geological data (distance to fault map
and ophiolite outcrops map). The research included a comparison and discussion on the statistical and geological findings derived from different training dataset class ratios in relation to a testing dataset characterized by significant class imbalance. The results suggest that the precise selection of a suitable class balance for the training dataset is a critical factor in achieving accurate ophiolite prediction with RF and KNN algorithms. The analysis of feature importance revealed that the Bouguer gravity anomaly map, total intensity of the Earth’s magnetic field reduced to the pole map, distance to fault map, band ratio BR3 map obtained from multispectral satellite images, and digital elevation model are the most significant features for predicting ophiolites within the EVZ. KNN showed poorer results compared to RF in terms of both the evaluation
metrics and visual analysis of prediction maps. The methods applied in this research can be applied for predictive mapping of complex geo-tectonic units covered by dense vegetation, and may indicate the presence of these units even if they were not previously mapped, particularly when geophysical data are used as features.

AB  - The paper presents a nonlinear concentrated plasticity frame element for advanced analysis of steel frames exposed to elevated temperatures. The element extends the formulation based on the generalized plasticity material model that was successfully applied to the analysis of steel and composite structures. It considers the material's nonlinear behavior, temperature-induced loading, strength and stiffness degradation typical for structures under fire conditions. The nonlinear geometry is taken into account with the corotational formulation. Because of the generalized plasticity relations adoption, the element can describe the gradual yielding of cross sections. At the same time, the implemented return mapping algorithm ensures the element's high computational efficiency. The governing element equations, selection of parameters and computer implementation are discussed in the paper, followed by element validation through the number of experimental data examples and other numerical models. The comparative analysis demonstrated the element's versatility and capability to accurately predict the structural response of steel frame structures exposed to fire.

AB  - Masonry structures in addition to their long heritage are still widely used in civil engineering practice. It should be emphasized that a lot of research has already been done on the seismic behavior of masonry structures. However, due to the nature of such a problem, its complexity and seriousness, the development of numerical models and their connection with experimental tests are always important. This is particularly significant considering their vulnerability to the action of horizontal forces generated during seismic excitations. In recent decades, many researchers have tried to capture the behavior of unreinforced masonry (URM) structures or reinforced concrete (RC) frames with masonry infills exposed to earthquakes, using different approaches. This paper tackles numerical modeling based on the finite element method (FEM) for the estimation of the dynamic response of two adjacent interacting URM units, subjected to shaking table motions. Geometrical and material properties of the specimen are provided by the Horizon 2020 project SERA-AIMS (The Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe – Seismic Testing of Adjacent Interacting Masonry Structures). The analyses of dynamic performance were executed in SAP2000 software. Obtained results on the numerical model provide useful guidelines for modeling the nonlinear seismic behavior of masonry buildings.

AB  - Nowadays, numerous experimentally, numerically and analytically based research have been
performed to evaluate the structural responses and ultimate capacity of beams with web
openings, but mostly under bending. However, in practice, the application of steel cellular
elements dominantly loaded by axial pressure is very common. With the lack of appropriate
design approaches, we rely on engineering judgement, which can result in uneconomic, time-
consuming, or unsafe solutions. To ensure the safety of a structure it is necessary to assess its
structural resilience.
An overview of the existing experimental study on compressed I-section short columns with web
openings, assessment of the impact of openings’ size and shape on cross-section deformation
and resistance capacity under pure compression was performed. To accomplish an adequate and
easy-to-use design method for hot rolled perforated columns, the design procedures stated in: (i)
draft version of new European code prEN 1993-1-13, (ii) the Direct Strength Method (DSM) in
American standard AISI S100-16 and (iii) the Continuous Strength Method (CSM) in prEN
1993-1-4 were evaluated based on experimental data, and the obtained outcomes are briefly
presented in this paper. Although none of these design methods include all aspects of observed
case – hot rolled perforated elements under compression (Eurocode has a strict limit of axial
force, CSM and DSM primarily refer to cold-formed steel sections and do not recognize the
existence of openings at all), they turned out to be quite accurate. The corresponding results were
obtained by modifying those procedures, so they better reflect a case of interest. Thus, DSM
method didn’t need any modifications, and CSM had the most.

AB  - Ground floors of industrial buildings, fully supported on the ground or piles, are usually made
of several concrete segments connected through free-movement construction joints. These joints
should provide shear load transfer of the slab and minimise its vertical displacements while
allowing slab horizontal movement to prevent damage due to concrete dry shrinkage. The
construction joint “Dilat 08”, consisting of round steel dowels and steel formwork, was
experimentally tested in a laboratory environment to determine its behaviour to shear load. The
experimental double-shear setup consisted of three slabs connecting through the “Dilat 08” join
system, with two side slabs fully supported on the base and the middle slab on which the vertical
loading was applied. Specimens were formed with a gap of 10 mm between adjacent slabs to
simulate the construction joint opening. Two construction joint orientations were investigated
introducing the vertical load to the slab with a steel plate on the edge and to the slab with an
angle profile on the edge. Experimental testing of both specimens resulted in construction joint
failure due to concrete cracking around steel dowels, near the edges of the middle slab. The
investigation confirmed that the joint orientation affects the joint shear response, demonstrating
larger joint resistance when the steel plate is installed in the slab subjected to failure. Although
contributing to the joint bending stiffness before formwork installation on the site, the horizontal
leg of the angle profile decreases the joint resistance. Experimentally obtained joint resistance
was compared to the design values of resistance according to Technical Report 34 and EN 1992-
4, highlighting a considerable difference between the two analytical approaches. The comparison
between the “Dilat 08” and three types of free-movement joints available on the construction
market showed that “Dilat 08” features larger resistance according to Technical Report 34, but
it also weighs more.

AB  - When analysing the fire resistance of the steel structure of the stadium roof in the event of a fire,
the specific features of the stadium building must be taken into consideration. The stadium stands
are open units of the building that are directly connected to the surrounding area. The clear height
between the stadium roof and the stands is commonly large. However, the clear height between
relatively small parts of the roof, directly above the top of the stands, could be smaller, potentially
making this part of the roof the most vulnerable. On the stands of the stadium, it is prohibited to
bring items that contain combustible material. In addition, the structure of the stadium, benches
or chairs must be made of non-combustible material. Therefore, a fire that could compromise the
steel structure of the stadium roof can only come from the stadium premises on the stands or
under the stands. The fire scenarios on the stadium roof are not described in detail in the literature
compared to indoor (covered) sports arenas. To assess the fire resistance of the roof structure, it
is necessary to check all possible and potentially dangerous scenarios. The subject of the analysis
presented in this paper is the roof steel structure of the stadium in Loznica, Serbia, which was
built in the period 2021–2023. The study considers the following fire scenarios and their effects
on the roof steel structure: (i) a local fire on the stands, and (ii) a fire in the stadium premises
affecting the external members. The fire in stadium premises was analysed using the analytical
expressions provided in Annex B of EN 1991-1-2 and EN 1993-1-2, as well as through CFD
(Computational Fluid Dynamics) analysis of fire propagation. The calculation was performed
for the domains of temperature, time and resistance, depending on the applied fire load analysis.
Results showed that the steel structure of the stadium roof in Loznica meets the load-bearing
codified criteria for the fire effects, with the exception of only one main roof truss. To address
this issue, it was decided to install fire-resistant glass in the TV studio on the building's third
floor to separate this area from the stands and prevent fire effects on the critical main roof truss.

AB  - Driven by the industry's needs to address energy dissipation issues in mechanical connections,
the set goals of the global scientific community, and previous research efforts to interpret how
the condition of contact surfaces between two bodies in contact can be significant, a unique
experimental setup has been devised to study the impact of the state of contact interaction
between two bodies on the system's response. The purpose of the designed experimental setup
is to correlate the roughness of contact surfaces with the deformation of a specially designed
experimental sample. The roughness of contact surfaces represents the most dominant
influencing factor in the contact interaction of two bodies. In terms of scale, the study,
measurement, and analysis of surface roughness fall under the micro and nano scales. On the
other hand, the change in deformation of the experimental sample as a result of the change in
roughness falls under the macro scale. Based on all the aforementioned, the fundamental idea of
the designed experimental setup can be seen. Considering that it is not possible to enter into
contact interaction and explicitly analyse the influence of roughness on the response of a
mechanical connection, the idea in overall research is to consider the macro behaviour of a
specially prepared experimental sample depending on the level of roughness of the contact
interaction surfaces at the micro level. The aim of this paper is to present details and challenges
in the construction of an instrument necessary for such precise examinations, named “Precision
Press with Arcs”.

AB  - The paper presents an experimental and analytical way of determining the impulse response of
a linear time-invariant damped system with one degree of freedom.
An experiment was conducted where the mass was excited by an impact load. Both the mass
acceleration and impact force values were recorded. The magnitude of the system's frequency
response was determined based on the recorded values, ensuring the relatively simple
identification of the system's basic parameters. Those parameters were used to define a suitable
mathematical model of the system, transfer function, and frequency response function in an
analytical form.
The impulse response of the system based on the recorded values of mass acceleration and impact
load is expressed as a discrete function. This function is determined by applying the inverse
discrete Fourier transform of the corresponding frequency response function.
The impulse response of the system, based on the mathematical model, is expressed as a
continuous function. This function is determined by applying the inverse Fourier transform of
the corresponding frequency response.
Finally, it was shown that the response of a system to arbitrary load could be determined by
convolving the impulse response of the system with the load function. Convolution of continuous
functions is difficult to perform, and it can be used only for the simplest problem and for
understanding the physical phenomenon. Discrete convolution has a practical utility because it
is easy to perform in some program languages like Matlab. However, discrete impulse response
has limitations depending on the test conditions.

AB  - The paper presents part of the conducted research on laser-displacement sensors for the
measurement of structural response in civil engineering applications. Usually, the level of
displacement in laboratory or on-site testing is in small to mid-range levels of 1.00 to 25.00 mm
and in the frequency range of up to 100 Hz. Appropriate sensors were selected and used
according to performance in the sense of resolution/accuracy.
Experiments are conducted on steel model beam in the laboratory and on-site real bridge
structure. In both analysed cases, data analysis was carried out in the sense of modal frequencies
and damping estimation with comparison with numerically computed values.
Presented are the results of two experiments, a laboratory-tested model of steel beam and an onsite
tested real bridge structure. In both cases have achieved good argument of test results,
estimated modal frequencies and damping of tested model/structure.
Data analyses conducted used a developed MATLAB script, while the numerical computation
conducted used SAP2000_v14 FEM package for structural analysis.
Excellent agreement of extracted results was achieved in the case of the laboratory-tested
structural model, as well as of extracted results of on-site tested real-world structure in the sense
of extracted modal frequencies and modal damping.
Finally, the conclusion is that laser-displacement sensors are quite appropriate for small to midrange
of expected displacement and are quite appropriate for such applications according to the
possibility of installation so that such sensors could be applied for structural testing, particularly
for dynamic testing of such structures because of their possibility of high sampling frequency
and high resolution/accuracy.

AB  - Multi-model combination (averaging) methods (MMCMs) are used to improve the accuracy of hydrological (precipitation-runoff) outputs in simulation or forecasting/prediction modes. In this paper, we examined if the application of MMCMs can improve model performance in reproducing distributions of hydrological signatures, such as annual maxima or minima of varying durations. To this end, ten MMCMs were applied to 29 bucket-type models to simulate runoff in 50 high-latitude catchments. The MMCMs were evaluated by comparing the resulting simulated flows to the reference (i.e., best-performing) individual model, considering various commonly used performance indicators, as well as model performance in reproducing the distributions of signatures. Additionally, we analysed whether (1) the selection of the candidate models, or (2) targeting specific signatures, such as annual maxima or minima, can improve performance of the model combinations. The results suggest that the application of MMCMs can improve accuracy of runoff simulations in terms of traditional performance indicators, but fails to improve performance in reproducing the distributions of signatures. Neither excluding poor-performing models nor applying the MMCMs with the targeted signatures, improves this aspect of model performance. These findings clearly reveal the need for further research aiming at enhancing model performance in reproducing the distributions of hydrological signatures, which is essential for climate-change impact studies.

AB  - The efficient way to mitigate the impact of the concrete industry on climate change is to reduce the clinker content in the concrete mix. Beside incorporating supplementary cementitious materials (SCMs), it is possible to use high filler content combined with concrete mix optimisation. Limestone powder emerges as a promising filler mineral due to its availability and ready-to-use technology. In this work, the carbonation resistance of concrete with a high limestone powder content (45–65% of the powder phase) was experimentally tested. Test results showed that, with an optimized mix design featuring low water content and increased paste and plasticizer volume, concrete mixes satisfied high workability and strength demands for commonly applied strength classes. However, carbonation resistance remains a challenge. After two years in indoor natural conditions, carbonation depths were 8%, 28%, and 67% greater than referent Portland cement concrete for mixes with 47%, 58%, and 65% limestone powder content, respectively. Further analyses showed the inapplicability of the existing fib Model Code 2010 service life prediction model to limestone powder concrete. Based on a comprehensive database of experimental results, the modification of the fib prediction was proposed. A full probabilistic service life analysis revealed that for concrete with more than 20% limestone powder content and for both 50 and 100-years’ design service life, the currently prescribed concrete cover depths in European standards should be increased, depending on the carbonation exposure class.

AB  - Fatigue analysis has an important role in evaluating the durability and performance of asphalt pavements, especially when novel or alternative materials are used. Numerous laboratory studies have investigated fatigue performance with the aim of estimating field behavior as accurately as feasible. Therefore, there are currently many different test methods and data analysis approaches that can be used. One of the most common laboratory test methods is the four-point bending beam (4PBB) test, which results are usually analyzed using the so-called traditional (where 50% reduction in initial stiffness is considered as failure criterion) or the energy ratio (ER) approach. However, outcomes from previous studies have shown that these approaches may not be appropriate and reliable if geogrids are used as a reinforcement. As a possible solution, this study proposes a new simplified flex point (SFP) approach that considers the flex point of the strain amplitude curve, measured during 4PBB fatigue tests, to calculate the number of cycles to failure. These three approaches were applied to four double-layered asphalt sets: one unreinforced and three reinforced with geogrids of different strength (50 x 50, 100 x 100 and 100 x 200 kN/m). The impact of reinforcement on the fatigue life was evaluated by comparing the critical strain values (ε6) of reinforced and unreinforced sets through the fatigue resistance improvement factor. The research findings showed that the use of geogrids improves fatigue life when the SFP and ER approaches are applied and that the traditional approach might not always be appropriate for assessing the fatigue resistance of reinforced asphalt mixtures.

AB  - Headed stud shear connectors are commonly implemented in steel-concrete composite floors for connecting the concrete slab to the steel beam and providing composite action between those two elements. The orientation of profiled sheeting is usually transverse or parallel to the supporting beam, and for those cases, design codes provide specific detailing requests and relations for obtaining headed stud resistance. Nevertheless, design codes do not recognise specific configurations when the angle between profiled sheeting ribs and the beam is in the range between 0° and 90°, which is characteristic of irregular-shaped floor structures. Due to the lack of design recommendations for headed stud resistance in these cases, investigations of the effect of the rib-to-beam angle on headed stud shear performance were conducted and presented in this paper. Experimental work included push-out tests conducted on specimens with rib-to-beam angles of 45° and 60°, as well as control specimens with ribs transverse to the beam. The influence of varied rib-to-beam angles on shear connector properties such as shear resistance, stiffness, ductility, and failure mode was discussed. According to experimental research, finite element models of push-out tests were created and verified. The parametric numerical analysis covered key parameters such as concrete class, headed stud height and diameter, and rib-to-beam angle. According to the results, an analytical relation for obtaining headed stud resistance in profiled steel sheeting with a rib-to-beam angle between 30° and 90° was proposed.

AB  - Flooding is expected to increase due to climate change, urbanisation, and land use change. To address this issue, Nature-Based Solutions (NBSs) are often adopted as innovative and sustainable flood risk management methods. Besides the flood risk reduction benefits, NBSs offer co-benefits for the environment and society. However, these co-benefits are rarely considered in flood risk management due to the inherent complexities of incorporating them into economic assessments. This research addresses this gap by developing a comprehensive methodology that integrates the monetary analysis of co-benefits with flood risk reduction in economic assessments. In doing so, it aspires to provide a more holistic view of the impact of NBS in flood risk management. The assessment employs a framework based on life-cycle cost-benefit analysis, offering a systematic and transparent assessment of both costs and benefits over time supported by key indicators like net present value and benefit cost ratio. The methodology has been applied to the Tamnava basin in Serbia, where significant flooding occurred in 2014 and 2020. The methodology offers valuable insights for practitioners, researchers, and planners seeking to assess the co-benefits of NBS and integrate them into economic assessments. The results show that when considering flood risk reduction alone, all considered measures have higher costs than the benefits derived from avoiding flood damage. However, when incorporating co-benefits, several NBS have a net positive economic impact, including afforestation/reforestation and retention ponds with cost-benefit ratios of 3.5 and 5.6 respectively. This suggests that incorporating co-benefits into economic assessments can significantly increase the overall economic efficiency and viability of NBS.

Besides the flood risk reduction benefits, NBSs offer co-benefits for the environment and society. However, these co-benefits are rarely considered in flood risk management due to the inherent complexities of incorporating them into economic assessments. This research addresses this gap by developing a comprehensive methodology that integrates the monetary analysis of co-benefits with flood risk reduction in economic assessments. In doing so, it aspires to provide a more holistic view of the impact of NBS in flood risk management. The assessment employs a framework based on life-cycle cost-benefit analysis, offering a systematic and transparent assessment of both costs and benefits over time supported by key indicators like net present value and benefit cost ratio. The methodology has been applied to the Tamnava basin in Serbia, where significant flooding occurred in 2014 and 2020. The methodology offers valuable insights for practitioners, researchers, and planners seeking to assess the co-benefits of NBS and integrate them into economic assessments. The results show that when considering flood risk reduction alone, all considered measures have higher costs than the benefits derived from avoiding flood damage. However, when incorporating co-benefits, several NBS have a net positive economic impact, including afforestation/reforestation and retention ponds with cost-benefit ratios of 3.5 and 5.6 respectively. This suggests that incorporating co-benefits into economic assessments can significantly increase the overall economic efficiency and viability of NBS.",

and this includes the appropriate dimensioning of anchor supports, i.e. suppor elements, within the
framework of the concrete construction project. Bearing in mind the great variations in soil qualiy
and different ambient conditions that depend on the location, different ways of dimensioning have
been developed, from experiential, through those defined based on soil conditions and theoretical
models, and to numerical ones characterized by the appropriate degree of accuracy. The paper
presents the principle of in situ testing of the load capacity of trial anchors using specially
