AB  - The Golubac Fortress was built at the very entrance of the Iron Gates gorge, at the point where the Danube is the widest in its course and transitions into the narrow passage of the Carpathian Mountains. The fortress represented an important medieval military border stronghold, strategically constructed due to the military significance of the location. Because of its position, during the 14th and 15th centuries, bordering countries, Hungary and Serbia, and later the Ottoman Empire, fought to conquer the Golubac Fortress in order to gain control and power over the state border.
There are no exact records of who and when initially built the Golubac Fortress. The first mention in written sources is from the year 1335, in a Hungarian charter from 1337, which states that the nobleman Nikola Banfi resided in Golubac in 1335. Until the dissolution of the Dušan’s Empire, Golubac Fortress status remains unchanged according to historical sources, and it remains in Hungarian possession.
At the beginning of the 21st century, the town of Golubac was in very poor condition, neglected and inaccessible. Reconstruction of the entire Golubac Fortress began in 2011. The reconstruction was officially completed in 2019. However, some minor reconstruction and revitalization work is still ongoing today.
The foundation of the Golubac Fortress was adapted to the terrain's configuration and consists of 9 towers connected by the ramparts and the Palace. As part of the restoration efforts, all the towers, ramparts, and the Palace were reconstructed.
The paper depicts the reconstruction of the entire Palace, including its foundations and a new roof structure made of glued laminated timber.

AB  - In this paper an efficient procedure for obtaining a cohesive law for Mode I timber fracture (crack opening), based on the Double Cantilever Beam (DCB) tests is given. DCB tests were performed on ten European spruce specimens in order to determine the energy release rate vs crack length (R curves). Two crucial parameters - crack length during the experiment and the crack tip opening displacement were obtained using 2D Digital Image Correlation (DIC) technique. In order to determine accurate fracture resistance (R curve), procedure which includes calculating cumulative released energy was employed. The cohesive law for Mode I fracture of wood was obtained by differentiation of the strain energy release rate as a function of the crack tip opening displacement. This cohesive law is further implemented in the successful numerical modelling of failure modes in large-scale end-notched glulam beams which were experimentally tested in four-point bending configuration.

AB  - Cross-laminated timber (CLT) is an innovative engineering wood product made by gluing layers of solid timber boards placed in an orthogonally alternating orientation to the neighbouring layers. CLT panels provide an efficient solution for floors in single- and multi-storey buildings. Due to their light weight and often long-span, the design of these floors is generally governed by serviceability limit state criteria, that is, deflection or vibration limits. Vibrations induced by dynamic actions, such as people walking and their everyday activities, cannot result in structural failure but may cause discomfort to occupants if vibrations are not properly controlled. This paper gives an overview of some available methods for the vibration serviceability design of residential CLT floors. Differences between these methods are discussed through the consideration of criteria and their limit values. Although some criteria are common to certain methods, it may happen that the same criteria take into account different factors. In order to get a better description of the actual behaviour of floor structure, certain classifications of floors based on vibration serviceability performance were introduced in design methods.

AB  - Cross laminated timber (CLT) is relatively new engineering wood product made by gluing cross-wise layers of solid timber boards to form large-scale panels. Due to excellent in-plane and out-of-plane resistance, CLT panels have become very common as wall and floor structural elements. CLT is validated as an excellent alternative to more traditional construction materials like reinforced concrete and steel for use in single- and multi-storey buildings.
This paper presents an experimental study conducted on five-layer CLT panels manufactured using spruce boards. The panels were tested in four-point bending configuration, loaded in the out-of-plane direction. Bending behaviour of CLT panels in the major axis orientation was evaluated through failure modes, load-deflection relationship, ultimate moment capacity, stiffness and strain distribution profile. The obtained experimental results indicated brittle failure modes and linear load-deflection relationship up to failure. In addition, strain distributions of panels were quite linear during the entire loading, confirming the assumption that plane sections remain plane after bending.
Bending response of CLT panels was also investigated using finite element modelling. The stress and deflection analysis was executed in the RFEM software using the RF-LAMINATE module. The calculation was carried out according to the laminate theory, taking into account shear coupling of layers. A good agreement between the results of numerical model and experimental investigation was found.

AB  - This paper presents an experimental procedure for obtaining the fracture resistance (R curve) of solid wood specimens made of spruce. Double Cantilever Beam (DCB) tests were performed in order to determine energy release rate vs crack length in Mode I wood fracture (crack opening). Ten wood specimens were loaded using the Universal Testing Machine and force-displacement curves were recorded. The most important parameter - crack length was monitored as the crack propagates using Digital Image Correlation (DIC) method. In order to obtain accurate R curve results, procedure which includes calculating cumulative released energy was employed. The cohesive energy Gf was determined based on the R curves. These results can further be analysed in order to obtain cohesive law for Mode I fracture of wood.

AB  - Cross laminated timber (CLT) is an innovative engineering wood product made by gluing layers of solid timber boards placed in orthogonally alternating orientation to the neighbouring layers. CLT panels provide an efficient solution for floors in single- and multi- storey buildings. Due to the light-weight and often long-span, design of these floors is generally governed by serviceability limit state criteria, that is deflection or vibration limits. Floor vibrations induced by dynamic actions, such as people walking, do not result in structural failure but may cause discomfort of occupants if the vibrations are not properly controlled. This paper gives an overview of some available methods for vibration serviceability design of residential CLT floors. Differences in considered parameters and limit values of these methods are discussed.

AB  - End-notched timber beams can have a significant decrease in load-carrying capacity as a consequence of stress concentration due to height reduction at the supports. To prevent crack opening and its propagation at the notches, these beams are usually reinforced. In this paper, extensive experimental research on end-notched glulam beams reinforcement with glass fibre reinforced polymer - GFRP bars is presented. Bending tests on unreinforced and reinforced end-notched glulam beams were carried out until the point of failure. Behaviour of tested beams is described through load–deflection diagrams, failure modes and ultimate loads. In addition, different reinforcement schemes of notches were analysed in order to determine an optimal configuration under the aspect of load-carrying capacity improvement in relation to the unreinforced beams. The effectiveness of GFRP bars as a reinforcement of end-notched glulam beams was evident from significantly increased ultimate load and deformability. The design procedures for unreinforced end-notched beams according to Eurocode 5 and reinforced end-notched beams according to German national annex of Eurocode 5 were analysed through comparison with the experimental results. Recommendations for the design of GFRP reinforcement are given.

AB  - Human-induced vibrations of timber floors are considered to be a serviceability issue that primarily
relates to discomfort of occupants. These vibrations are particularly problematic because they happen frequently and cannot be isolated. Vibration serviceability of timber floors is becoming more relevant due to increased demand for building new floor systems with larger spans. There are a number of different design methods with regard to vibration problems and there are a number of studies developed to improve these methods. This paper presents the design method for vibrational serviceability of timber floors proposed in Eurocode 5 Part 1-1. The vibrational parameters which need to be checked include fundamental frequency, unit point load deflection and unit impulse velocity response. The criteria defined in Eurocode 5 are regulated in the National annexes of each member country. Presentation and comparison of different design practices with regard to vibration performance of timber floors according to Eurocode 5 among European countries are made. Even though Eurocode 5 has given general criteria for vibrational serviceability design of timber floors, the design equations and design limits vary largely from country to country due to different tolerances for vibration disturbance as well as different construction practices. Design rules for human-induced floor vibrations in the current Eurocode 5 are predicated based on a correct philosophy but it remains to be demonstrated that these rules with some modifications can be applied beyond the context of traditional solid timber joist floors with decking.

AB  - Load carrying capacity of end-notched timber beams can be significantly decreased depending on the geometry of notches. Concentration of tensile stresses perpendicular to grain and shear stresses at the notch corner can cause crack opening. Since uncontrollable crack growth leads to premature failure of notched timber elements, reinforcement is advisable. This paper presents a finite element based numerical analysis of bending behaviour of endnotched glulam beams reinforced with GFRP (Glass Fibre Reinforced Polymer) bars developed in commercial software
Abaqus. Cohesive Zone Modelling (CZM) is employed to simulate the crack growth phenomenon. Verification of the proposed model is done through comparison with experimental research. Fairly good agreement between numerical and experimental results proved that the developed model is successful in predicting the behaviour of reinforced notched timber beams. The presented model can be used for further parametric analyses and serve as a basis for investigation of other types and positions of reinforcement, while being a useful tool for development of appropriate analytical design methods for reinforced end-notched timber elements.

AB  - Sustainable design, alongside environmental awareness, is increasingly becoming a requirement
for building construction. Since the construction industry represents one of the biggest sectorial
emitters of greenhouse gases, causing anthropogenic climate change, application of sustainable
and/or natural materials for buildings is advisable as a significant mitigation measure. In
comparison to traditional energy-intensive construction materials, such as steel and concrete,
wood-based materials consume less energy and emit fewer greenhouse gasses and pollutants
over their life cycle. Building with timber has multiple advantages when environment is
concerned: regionally available resource, renewability, smaller carbon footprint, lighter
structures, prefabrication, faster erection on site, recycling possibilities etc.
Considering the aforementioned, it is very important to spur innovation, research and
development of wood as a construction material. Increased interest in green buildings has
influenced an increase in use of wood materials and more developments in the wood products
sector. Major emerging products from the timber industries include GLULAM, NLT, DLT,
massive veneer panels and CLT, with CLT being the one studied the most. Introduction of
CLT, with its structural capability and improved properties, provided the necessary stiffness
and made it feasible to use wood in construction of mid-rise and tall buildings (>10 storeys),
industrial structures, and bridges.
Since the world’s population is increasing and urban areas are growing denser, there is a
constant need for high-rise buildings, and taking into account that environmental awareness
requires the use of eco-friendly materials, design and construction of high-rise wooden
buildings inevitably becomes a necessity for the modern age.

abstract = "Sustainable design, alongside environmental awareness, is increasingly becoming a requirement
for building construction. Since the construction industry represents one of the biggest sectorial
emitters of greenhouse gases, causing anthropogenic climate change, application of sustainable
and/or natural materials for buildings is advisable as a significant mitigation measure. In
comparison to traditional energy-intensive construction materials, such as steel and concrete,
wood-based materials consume less energy and emit fewer greenhouse gasses and pollutants
over their life cycle. Building with timber has multiple advantages when environment is

AB  - In this paper damages and rehabilitation of bridge across Lepenica River in Kragujevac are
presented. The bridge is reinforced concrete tied-arch structure. Main girders (two arches) have
a span of 31.5 m and they are supported by massive riverside columns. Bridge deck is
composed of a deck slab and secondary longitudinal and transverse girders. The transverse
elements are overhanging beams, with the slab on the overhangs representing footpaths. The
bridge was built in 1923. Due to inadequate maintenance and exposure to adverse climatic
conditions, damages of deck, secondary longitudinal and transverse beams, main supports
(arches, tie beams, hangers), bearings and expansion joints have occurred. In order to ensure
lasting stability, safety and functionality, certain repair interventions had to be undertaken. In
the previous period, various bridge repairs have been performed, the last one being in 1998.
The main damages of structural elements were concrete protective layer degradation, corroded
reinforcement and occasional cracks. The damaged concrete surface was completely removed,
until healthy parts were reached. The concrete was sandblasted and the reinforcement was
cleaned of corrosion. The reinforcement was protected using the appropriate material, with
bonding coating and repair mortar applied afterwards. Footpath decks have been significantly
damaged, and there were even "caverns" where the concrete was completely destroyed. Repair
was done by completely removing the existing slabs and replacing them with new ones.
Due to moisture and reinforcement corrosion, the joints between the hangers and the tie beams
were particularly vulnerable. During the previous repairs, steel frames were attached around the
tie beams and connected to the hangers. The most serious damages occurred on the bottom of
individual frames. Damages were manifested as separation of parts of the steel elements, which
significantly reduced the cross-sections. All steel frames were sandblasted and cleaned from
corrosion. For steel frames requiring more serious repair, new steel profiles were mounted.
Afterwards, the frames were protected by appropriate anti-corrosion coatings.
The extent of damages to the expansion joints required their replacement.

AB  - In this paper damages and repair interventions of the indoor swimming pool structure in
Kruševac, Serbia are presented. The facility is composed of main part and annexes, built in
reinforced concrete and timber. The roof structure is made of glulam Gerber beams over two
spans 35 + 15 m, supported by interior timber columns. The annex load-carrying structure
consists of glulam beams, supported by reinforced concrete structure and timber columns.
The pool was built in 1982, and due to inadequate maintenance and exposure to adverse climatic
influences, significant damages to roof cladding, secondary structural elements and
main girders occurred. In the past, due to wood degradation and other damages, some repair
interventions were undertaken. These interventions did not have the expected positive outcomes
and resulted in closing of the pool for public.
The repair interventions included replacement of the entire roof cladding, replacement and
repair of damaged timber elements, repair and reinforcement of steel connection elements.
Firstly, structural rehabilitation was performed to reduce stresses and deformations in certain
parts of the structure. The glulam girders were supported by new steel columns, which
almost completely relieved the existing timber columns. In addition, new steel columns were
added to the annexes. Cracks in timber elements were injected with two-component epoxy resin
of appropriate viscosity and mechanical properties. The epoxy resin was also used as a filling
at the places where rot was removed within the beams and columns in the support zones.
Larger rot damages on the lateral sides of the beams were repaired by removing damaged
laminations, and then gluing new ones using resorcinol glue. All steel elements that had significant
corrosion were replaced, and others were cleaned of rust and re-protected.
As a conclusion, guidelines are given for monitoring and maintaining the facility during further
exploitation.

AB  - In this paper, an experimental research on bending behaviour of end-notched glulam beams and their bending behaviour after repairing with glass fibre reinforced polymer (GFRP) bars is presented. Altogether five glulam beams (100 x 220 x 4000 mm) made of spruce timber classified in the strength class C22 were tested. Experiment showed that originally, the beams failed in a brittle manner due to crack opening and its propagation. Cracks in the notch details were a result of excessive tensile stresses perpendicular to grain and shear stresses. Repairing the beams with GFRP bars after their failure completely restored and notably improved their load carrying capacity (average increase of 194%). Failure mechanism after repair changed from the original brittle tensile failure to more ductile failure in bending for most beams, proving the successfulness of the intervention. This study gives an insight in rehabilitation and repair possibilities of existing structures using advanced materials like GFRP bars.

AB  - Load carrying capacity of solid timber and glued laminated timber (glulam) beams is significantly decreased if there are notches made at the supports. Sudden change in cross-section height (notch) results in deviation of stresses leading to concentration of tension perpendicular to grain and shear stress in a notch corner, which causes crack opening and its growth. With load increasing, uncontrollable crack growth due to low resistance in shear and tension perpendicular to grain of wood, as well as brittle failure mechanisms as a result of these actions, can lead to failure of a beam. Therefore, notches should generally be avoided, and when unavoidable, notches should be reinforced. This paper presents a finite element based numerical investigation of bending behaviour of end-notched glulam beams reinforced with traditional screws for timber. Commercial software Abaqus was used for modelling of reinforced end-notched glulam beams subjected to bending. Cohesive Zone Modelling (CZM) was employed to simulate the crack growth phenomenon. Cohesive behaviour in the fracture region was defined through appropriate traction-separation law, while failure of elements was characterized by a progressive degradation of material stiffness which is driven by a damage process. Verification of the proposed model was performed through comparison with experimental tests. Good agreement was found between numerical and experimental results, proving that the developed model is successful in predicting the behaviour of reinforced notched timber elements. The numerical modelling, as well as the experimental research, can help in better understanding of the crack initiation and crack growth phenomenon in reinforced end-notched timber beams. Also, effectiveness of screws as reinforcement od end-notched glulam beams has been proven. Initial cracking of the notch corner cannot be prevented by the reinforcement. However, by placing screws uncontrollable crack growth was limited and load-carrying capacity and deformability of beams were increased.
The presented model can be used for further parametric analyses, which would include varying the loading configuration, geometry, material properties and types and positions of reinforcement. In addition, results obtained from FEM modelling can be useful in developing appropriate analytical design models for reinforced end-notched timber elements.

AB  - Notches made at the ends of glued laminated timber (glulam) beams significantly decrease load carrying capacity of a structural member. This paper presents an experimental research on bending behaviour of end-notched glulam beams, and their bending behaviour after they were repaired using screws. The beams originally failed due to crack opening and their propagation. Cracks that appeared in the notch details resulted from excessive tensile stresses perpendicular to grain and shear stresses. This study showed that repairing the beams at the notched ends post failure can completely restore and even improve their load carrying capacity and successfully tie together the upper and lower parts of the beam separated due to horizontal crack that propagated from the notches towards the middle. Most repaired beams failed in bending while exhibiting ductile behaviour. However, there was no substantial improvement of bending stiffness. This research gives an insight in rehabilitation and repair possibilities of existing structures and it can be a basis for further investigation of strengthening techniques for end-notched solid timber and glulam beams.

AB  - Notches made at the ends of timber beams significantly decrease load carrying capacity of a structural member. This paper presents an experimental research on bending behaviour of end-notched glulam beams, with and without reinforcement. Screws for timber were used as reinforcement, positioned at angles of 90° and 45° to the longitudinal beam axis. The unreinforced beams failed due to crack opening and its propagation in a brittle manner. Cracks that appeared in the notch details resulted from combined excessive tensile stresses perpendicular to grain and shear stresses. This study shows that reinforcing the beams at the notched ends can improve their load carrying capacity and deformability. However, applied screws did not help the beams achieve ductile failure in bending. The shear failure was dominant failure mechanism for reinforced beams. In addition, analytical calculations were performed in accordance with Eurocode 5 so as to compare the results with experimental research.
AB  - Redukcija visine drvenih nosača kod oslonaca znatno umanjuje kapacitet nosivosti elementa. U ovom radu je predstavljeno eksperimentalno ispitivanje lepljenih lameliranih drvenih nosača sa redukovanom visinom preseka kod oslonaca opterećenih na savijanje, sa i bez ojačanja. Kao ojačanje upotrebljeni su zavrtnji za drvo, postavljeni pod uglomod 90° i 45° u odnosu na podužnu osu nosača. Neojačni nosači su doživeli krti lom usled otvaranja pukotine i njene propagacije. Ove pukotine su rezultat prekoračenja čvrstoće drveta na zatezanje upravno na vlakna i čvrstoće drveta na smicanje. Ispitivanje je pokazalo da se upotrebom zavrtanja može povećati kapacitet nosivosti i deformabilnosti posmatranih nosača. Međutim, primena zavrtanja kao ojačanja nije dovela do promene oblika loma iz krtog u duktilni lom usled savijanja. Lom usled smicanja je bio dominantan oblik loma kod ojačanih nosača. Takođe, analitički proračun je izvršen prema Evrokodu 5 kako bi se rezultati uporedili sa eksperimentalnim ispitivanjem.
