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  - Cross-laminated timber (CLT) floors have gained in popularity due to their outstanding strength,
aesthetic appeal, good fire resistance, and high level of prefabrication. However, due to their
high stiffness-to-weight ratio, CLT floors are highly susceptible to pedestrian-induced
vibrations. In design practice, vibration serviceability is usually assessed by assuming a floor as
a set of CLT panels with no inter-panel connections, which leads to overestimation of the
vibration response. In this paper, an experimental dynamic testing was carried out to identify
modal properties and pedestrian-induced response of two CLT floors with different number of
panels in a floor assembly. Influence of the inter-panel connections on the floor modal properties
and pedestrian-induced vibration response is particularly studied and discussed.

AB  - The objective of this research is to develop a numerical model of one widely used bolted beam splice connection
that dissipates energy through structural damping. The reference experimental setup is carefully designed to
obtain the highly nonlinear dynamic response due to the suddenly released load. The fact that the monolithic
beam with welded connection has a linear response is utilized for the initial calibration of the numerical and
experimental models. Then, the numerical model of bolted beam splice connection is verified and adopted
through an iterative process. The influences of time and spatial integration, bolt load application, element
type, contact formulation, bulk viscosity, and mass scaling are discussed. A special attention is given to the
load application and load release functions. After the verification, the Abaqus/Explicit numerical model is
validated through the comparison with experimental data, where an appropriate friction coefficient is adopted.
It is demonstrated that the nonlinear structural damping occurs due to the complex micro slip behavior at the
contact interface.

AB  - The paper presents testing of two piles, diameter of Ø1200mm and Ø800mm, length of 26.0m
and 18.0m respectively. Tests were conducted on construction project WELLPORT III phase -
New Belgrade, Republic of Serbia. The piles were erected using CFA technology by Novkol
jsc. - Belgrade. The tests were conducted according to the standard SRPS EN ISO 22477-1:
2019, jointly by the Laboratory for structures of the Faculty of Civil Engineering University of
Belgrade and Laboratory of Novkol jsc. - Belgrade. In addition, beside to the common and
inevitable measurement of pile settlement with respect to the applied load during test phases,
tests include measurements of strain along the pile depth. Measurements of strain were carried
using so-called ‘sister-bar’ based on resistance principle (classical foil strain gages), as well as
using embedded sensors based on ‘vibrating-wire’ principle of strain measurement, as both
principles of strain measurements are state-off-the-art in actual practice. Installation of all
instruments were incorporated in pile reinforcement assembly at several levels before casting.
During testing, beside to recording force at pile head and settlements by LVDTs which were
leaned on the reference beam, there were recorded and realized strain levels on all installed
instruments. During data reduction phase, computation of actual force was realized at each
section with strain measurement, based on axial stiffness of tested piles. Using such a
procedure, forces in tested piles were calculated. Such data gave possibility to explore part of
force which was transmitted by pile shaft along the depth to the surrounding soil, as well as the
part which goes to the pile base. All results are shown in illustrative diagrams of corresponding
stresses between pile shaft and surrounding soil, force levels along the pile depth, and finally
level of force which transfer by pile shaft and pile base. According to the facts that pile bases
were in different soil level, and with different diameters, the different ratio between force
levels which transferred by pile shaft and pile base were established.

and 18.0m respectively. Tests were conducted on construction project WELLPORT III phase -
New Belgrade, Republic of Serbia. The piles were erected using CFA technology by Novkol
jsc. - Belgrade. The tests were conducted according to the standard SRPS EN ISO 22477-1:
2019, jointly by the Laboratory for structures of the Faculty of Civil Engineering University of
Belgrade and Laboratory of Novkol jsc. - Belgrade. In addition, beside to the common and
inevitable measurement of pile settlement with respect to the applied load during test phases,
tests include measurements of strain along the pile depth. Measurements of strain were carried
using so-called ‘sister-bar’ based on resistance principle (classical foil strain gages), as well as
using embedded sensors based on ‘vibrating-wire’ principle of strain measurement, as both
principles of strain measurements are state-off-the-art in actual practice. Installation of all
instruments were incorporated in pile reinforcement assembly at several levels before casting.

AB  - When evaluating modal properties of lively structures as footbridges, numerical modelling
should be used with caution. This is due to model uncertainties mostly related to material
parameters, boundary conditions, the effects of the non-structural elements, and also other
inevitable differences between as-built and designed structures. Differences between the
dynamic behaviour of the as-built structure and the numerical finite element model are best
visible after performing vibration testing and modal properties identification based on
experimentally obtained results. Conclusions regarding reasons for these differences can be
useful for further understanding of vibrational behaviour of footbridge structures and can help
designers in better predicting dynamic properties of such structures in the design stage.
This paper describes a lively full-scale footbridge over the Vrbas river in Banja Luka, Prijecani
sub-area, Serbian Republic, Bosnia and Herzegovina, its modal properties estimation based on
ambient vibration measurements and numerical modelling.
Identification of modal properties was performed using Ambient Modal Testing applying
Multiple Test Setup Measurement Procedure and Frequency Domain Decomposition method.
The ambient vibration measurement technique for the subject footbridge, which gave a good
quality of the results obtained, is presented.
Analysis of the obtained experimental results is given, as well as their comparison with
numerically estimated values in the finite element model. Despite some irregular features of the
subject footbridge, correlation is obtained, and conclusions are made regarding the effects of
numerical model parameters on structural dynamic properties.

AB  - Adding fibre reinforcement to concrete has a beneficial effect on the structural integrity and durability, enables construction cost&time savings. Because of these advantages, fibre reinforced concrete is gaining an increasing interest in development and use both in novel structures, as well as for repair, rehabilitation and strengthening of the existing structures. In order to determine the properties of the fibre reinforced concrete, that are necessary for design according to current guidelines, standardized tests are performed - most often flexural (or bending) test, conducted on the prismatic samples. The paper presents the results and analysis of flexural strength tests of samples made of steel fibres reinforced concrete. This concrete has potential for use in elements of the structures which are under tensile stresses in exploitation.

AB  - Slip-resistant shear connections with preloaded bolts have traditionally been used in steel
structures exposed to cyclic. Hence, shear load is transferred through friction surfaces
rather than through contact between the bolt surface and the hole. The main influencing
parameters determining slip resistance of the connection are the friction between contact
surfaces and the bolt preload level. This paper presents an experimental study of preloaded
bolted connections under cyclic load, the main objective being to investigate the influence
of cyclic load on the losses of preload force in high strength bolts and lock bolts.

AB  - Problems involving contact are of great importance in industry related to
mechanical and civil engineering, but also in biomechanics and other applications. The
contact interaction between surfaces in a bolted splice connection joint or area through
which tire interacts with the road is not known a priori, leading to a nonlinear boundary
value problem. Due to the rapid improvement of modern computer technology, today one
can apply the tools of computational mechanics to analyze contact problems with limited
accuracy, depending on design requirements. However, even now most of the standard
finite element software is not fully capable of solving contact problems, including friction,
using robust algorithms. The aim of this paper is to present some basic concepts of Contact
Mechanics. To illustrate the difficulties arising in computational contact mechanics,
Newton-Raphson scheme was used to solve simple 1D contact problem using penalty
method.

AB  - This paper presents the finite element modeling of bolted joints for structural
dynamic analysis to achieve a reasonable accuracy in simulation results. Non-linear
effects in splice connected joints involve normal compressive loads holding components
together combined with dynamic lateral loads inducing some amount of shear slip in
contact interaction between elements of splice connection joint. The complexities of the
slip process are responsible for the nonlinear nature of the interfaces, both in terms of
stiffness and dissipation. Exploring the physics of joints directly is not readily done
because key interactions takes place at the interface of surfaces, where instrumentation
cannot be placed without changing the problem. Consequences of the specific conditions
of joint connections are increased dynamic problems related to vibrations and dissipative
processes in structure connection joints. Structural joints are the main reason for the
significant level of energy dissipation and source of structural damping. The aim of this
paper is to present some problems regarding research of structural damping and the
importance of study Contact Mechanics to better understand the problem of structural
damping.

AB  - The challenge that will be posed to researchers for an even longer period is
the development of a predictable model for describing mechanical connections, their
variable stiffness and dissipative contact interaction processes. The main challenge to this
goal lies in the lack of understanding of how friction behaves on a small scale. Coulomb
friction, a large heuristic model is not predictable and has actually been proven to be
untrue in many modes. Expecting a universal law of friction for all types of materials and
therefore contact interactions is not very realistic. Instead, the goal of the international
research community is to develop a predictable model for a limited range of cases. So far,
the metal-metal contact is most often tested, respectively the contact interaction behaviour
of aluminium and steel elements of different quality. We also know that in the application
those two metals are most often found in making mechanical connections. The aim of this
paper is to make a brief overview of some of the previous tests and approaches to the study
of contact interaction in mechanical connections and the role of friction in energy
dissipation.

AB  - The aim of this paper is to discuss numerical analysis and verification of experimentally tested bolted and weld splice connections in the commercial Abaqus software. The first step in verifying a numerical model with an experimental one is to compare the modal frequencies. The problems that arise when modeling multiple bodies in a contact interaction, such as in the case of bolted splice connection joint, arise from the behavior of the contact itself [2] and [1]. In order for the numerical model to be stable and without calculations convergence issue, it is necessary to: define an adequate type and size of finite elements, determine the master and slave surfaces, and properly define the constraints and connections of the separate parts of the bolted welded connection structure. Tests with a modal hammer were performed in order to find the oscillation tones of the cantilever beam under consideration, which would be compared with the numerical model. Based on a comparison of numerical and experimental results, it is discussed whether the experimental beam is adequately designed and constructed and the effects of the support and splice connections on the frequencies are considered.

AB  - Problems involving contact are of great importance in industry related to mechanical and civil
engineering, but also in biomechanics and other applications. The contact interaction between
surfaces and different bodies like in a bolted splice connection joint or area in which a tire interacts with the soil is not known a priori, leading to a nonlinear boundary value problem. Due to the rapid improvement of modern computer technology, one can today apply the tools of computational
mechanics to analyze contact problems with required accuracy, depending on design requirements. However, even now most of the standard finite element software is not fully capable of solving contact problems, including friction, with robust algorithms. The aim of this paper is to present some basic concepts of Contact Mechanich.

abstract = "Problems involving contact are of great importance in industry related to mechanical and civil
engineering, but also in biomechanics and other applications. The contact interaction between
surfaces and different bodies like in a bolted splice connection joint or area in which a tire interacts with the soil is not known a priori, leading to a nonlinear boundary value problem. Due to the rapid improvement of modern computer technology, one can today apply the tools of computational
mechanics to analyze contact problems with required accuracy, depending on design requirements. However, even now most of the standard finite element software is not fully capable of solving contact problems, including friction, with robust algorithms. The aim of this paper is to present some basic concepts of Contact Mechanich.",

AB  - Progress and demands of all types of constructions imposed the need for the development of modern structures that are lightweight, but at the same time have high damping capacity and stiffness. The consequences of these requirements are increased dynamic problems related to vibrations and dissipative processes in structure connection joints. Structural joints are the main reason for the significant reduction of the level of energy dissipation and source of structural damping so therefore they have become a subject of interest to many researchers. The aim of this paper is to present some problems regarding research of structural damping and the importance of study Contact Mechanics to better understand the problem of structural damping.

AB  - Paper presents research of short-term monitoring of vibration response of turbine table top foundation structure in Power Plant Nikola Tesla - A: unit A4 in Obrenovac – Republic of Serbia.
Research included short-term monitoring of vibration of the structure in ambient and in-operation
condition, numerical modelling of the structure according to available information of masses and
stiffness of structural elements, as well as extraction of mode shapes and operational deflection shapes.
Measurement of vibrations, during in and out of operating conditions, carried at the same set of points on the upper slab of foundation supporting structure using sensitive accelerometers in frequency range of 0 - 300 Hz, while acquisition carried out using 24-bits acquisition system.
Extraction of modes, frequencies and shapes, carried out using state of the art software package
ARTeMIS. The same extraction procedure applied for extraction of deflection shapes according to
acquired acceleration data during in-operation conditions. Numerical modelling performed using SAP2000 software package for structural static and dynamic analysis, with application of beam elements and additional masses with eccentricity from top level of the foundation structure. Additional masses, according to available data of weights of turbines, turbogenerator
and other installed equipment, are taken into account.
Finally, during analysis and comparison of experimental and numerical results, find out quite good
matches of mode shapes and operational deflection shapes, which clearly have been discussed in
conclusion.

AB  - The paper presents an analysis of the influence of vehicle speed movement
along bridge on dynamic amplification factor for the case of simply supported, continuous
and clamped beam structural system. The analysis was conducted analytically and
numerically. Theoretical expressions was developed for the case of movement a
concentrated force over the bridge over simply supported beam structural system, while
other cases were analyzed numerically. Two cases, movement of concentrated force and
system of concentrated forces were considered. The comparative results for the most
unfavorable case, with the valid domestic and foreign regulations, compared and
presented. The results showed that it is a more unfavorable case when vehicles are moving
at higher speeds on short-span bridges, as well as that one concentrated force produces
greater dynamic effects than a system of concentrated forces, as well as the simply
supported beam system is the most sensitive on dynamic loads respect to other structural
systems.
