SEISMIC ANALYSIS OF A TYPICAL FRAME OF A PREFABRICATED MULTI-STOREY CLT BUILDING
The increasing use of cross laminated timber (CLT) in modern construction is driven by its sustainability and favorable structural properties compared to concrete and steel. This paper investigates the seismic performance of a typical frame of a prefabricated four storey CLT building in a seismic region. The study assesses the dissipative behavior ...

POST-FIRE AXIAL CAPACITY OF RECYCLED AGGREGATE CONCRETE FILLED STEEL TUBE COLUMNS
The paper analyses the post-fire axial capacity of recycled aggregate concrete-filled steel tube (RACFST) columns. Since existing design codes lack guidelines for calculating this capacity, the modified method from the second-generation of Eurocode 4 is applied and its applicability is confirmed for RACFST columns. For method evaluation, the result...

EVALUATION OF THE MECHANICAL PERFORMANCE OF FOAMED CONCRETE USING THE SPECIFIC COMPRESSIVE STRENGTH-TO-DRY DENSITY RATIO
Owing to its low density, self-compacting capability, and thermal insulation properties, foamed concrete is widely used in lightweight construction. However, achieving an optimal balance between mechanical strength and dry density remains a major challenge in mix design. This study experimentally evaluated 32 foamed concrete mixtures incorporating ...

EFFECT OF RESISTANCE CRITERIA ON IMPERFECTION SENSITIVITY ASSESSMENT IN GNIA ANALYSIS
Eurocode requires the consideration of geometric imperfections. Imperfections can be considered directly, as is the case in GNIA and GMNIA analyses. Recent studies propose various methods for obtaining the governing imperfection, yet they rarely justify the criterion used to determine the buckling resistance from the nonlinear load-displacement cur...

DESIGN MODEL FOR CLT PANELS REINFORCED WITH GFRP BARS
Cross laminated timber (CLT) is relatively new and eco-friendly prefabricated wood product in a form of large structural panels used mostly for floors and walls. Cross-wise layer configuration enables both in- and out-of-plane resistance of CLT panels, providing significant structural flexibility. Modern structural demands, such as long-spans and h...

STRENGTHENING AND WATERPROOFING SOLUTIONS FOR BELGRADE RAILWAY TUNNELS: CASE STUDY
Water ingress is a major cause of deterioration in underground tunnel structures, particularly in ageing railway systems. This study presents the proposed solution for the rehabilitation of the Belgrade underground railway tunnel system, emphasizing both waterproofing and structural improvement. The analysis is based on real geological, geotechnica...

POST-FIRE ASSESSMENT AND REPAIR OF REINFORCED CONCRETE STRUCTURES: DAMAGE EVALUATION AND STRUCTURAL REHABILITATION
Although concrete is classified as a non-combustible material and generally exhibits good fire resistance, exposure to elevated temperatures may significantly reduce the mechanical properties of concrete and reinforcing steel, resulting in cracking, spalling, reinforcement degradation, excessive deformations, and, in severe cases, structural collap...

THE COLLAPSE OF THE CAROLABRIDGE – A TRAGIC INDIVIDUAL CASE?
The majority of small and medium-span bridges in Germany are made of prestressed concrete. All bridges are inspected at regular intervals to identify damage or load-bearing deficiencies at an early stage. Nevertheless, on September 11, 2024, the prestressed Carola Bridge in Dresden partially collapsed without prior warning. This article first provi...
