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 ...

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...

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 ...

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...

Broadway Subway Project u Vankuveru obuhvata izgradnju 5.7 km produženja metro linije sa više podzemnih stanica ispod jedne od najopterećenijih urbanih saobraćajnica. Duboki iskopi do približno 24 m, ograničen prostor, intenzivan saobraćaj i brojna komunalna infrastruktura predstavljali su ključne inženjerske izazove. Razvijen je modularni s...

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...

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...

A first in France: waterproofing of a rehabilitated highway Viaduct using Ultra-High Performance Fiber-Reinforced Concrete (UHPFRC). The rehabilitation of the Viaduct above Saône canal, on the A36 highway in France, provided an opportunity to implement an innovative waterproofing solution for a road bridge, based on the use of UHPFRC. The bri...

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 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...
