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...

ARTIFICIAL INTELLIGENCE IN STEEL STRUCTURES: METHODS, APPLICATIONS AND PERSPECTIVES ON JOINT BEHAVIOUR
Artificial intelligence (AI) is emerging as a powerful tool in structural engineering, enabling data-driven alternatives to traditional analytical and numerical methods. In steel structures, AI has been applied to design optimisation, structural health monitoring, and reliability assessment; however, its application to modelling nonlinear joint beh...

DURABILITY AND RELATED PROPERTIES OF CEMENT-BASED COMPOSITES CONTAINING CERAMIC WASTE TILE POWDER
The increasing environmental impact of cement production has driven the search for sustainable supplementary cementitious materials (SCMs). The incorporation of ceramic waste tile powder (CWTP) as a partial cement replacement in concrete and mortar has proven to be significant for durability and related properties improvement, enhancing the microst...

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...

ISTRAŽIVAČKI I KONZERVATORSKO-RESTAURATORSKI RADOVI NA STAROM GRADU BJELAJ
Stari grad Bjelaj (Bilaj), smješten u blizini Bosanskog Petrovca, predstavlja kompleksan fortifikacijski sklop sa slojevima prahistorijskog, srednjovjekovnog i osmanskog graditeljskog nasljeđa. Prema postojećim podacima, bedemi su građeni od lomljenog kamena zidanog u krečnom malteru, pri čemu su danas vidljiva značajna oštećenja nast...

BROADWAY SUBWAY PROJECT, VANCOUVER – MODULARNI SISTEM PRIVREMENIH KONSTRUKCIJA ZA DUBOKE URBANE ISKOPE
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...

VIERENDEEL BEHAVIOUR OF BEAMS WITH SINUSOIDAL WEB OPENINGS
This paper reviews the structural behaviour of perforated elements subjected to bending, with particular emphasis on the Vierendeel failure, which governs the resistance of these members. The stress distribution around web openings and the development of the Vierendeel failure mechanism are examined using experimental observations and finite elemen...

REHABILITATION OF THE A36 WARREN-TYPE VIADUCT
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...

BEFORE ANY INTERVENTION: THE CHALLENGE OF STRUCTURAL ASSESSMENT
Before any strengthening, repair, reconstruction or adaptation of an existing structure can begin, engineers face one of the most demanding tasks in practice: establishing its true condition. Structural assessment is far more than a routine inspection - it is an investigative process combining field observation, testing, material science, structura...

HAUNCH EFFECT ON STEEL FRAME ULTIMATE CAPACITY UNDER LATERAL LOADING
This paper investigates the effect of a haunch on the ultimate capacity and lateral stiffness of a single-bay, two-hinged, unbraced steel frame subjected to gravity loading and a concentrated lateral force. For the frame without haunches, analytical and numerical analyses were carried out using beam and shell finite elements, whereas the identical ...
