Concrete-filled steel tubes incorporating recycled aggregate concrete represent a sustainable composite structural members in which the steel tube provides effective confinement and enhances column performance. Although the experimental database for such members has grown in recent years, robust high–fidelity numerical models remain limited. ...

The reuse of structural steel elements is an effective strategy for reducing the environmental impact of construction. However, the practical application of reclaimed steel members may be limited by geometric incompatibilities between existing member dimensions and the requirements of new structural systems. The possibility of adjusting the effecti...

Cross-laminated timber (CLT) floors are increasingly used in long-span buildings as a greener alternative to reinforced concrete, steel and their composites. Despite high stiffness, relatively low mass of CLT makes such floors prone to pedestrian-induced vibrations. While these vibrations do not threaten structural integrity and safety, they often ...

The shear design of non-slender reinforced high-strength concrete (HSC) beams remains questionable, as indicated by experimental findings. This paper aims to perform a numerical simulation of a non-slender HSC beam and compare the results with experimental data. A finite element model of the tested HSC beam was developed in Abaqus, incorporating th...

This paper presents an assessment of the condition of the reinforced concrete structure of the stadium grandstands after many years of service and proposes recommendations to ensure its safe continued operation. The research focuses on deterioration of concrete and reinforcement in elements of the primary and secondary structural systems, including...

This paper investigates the fatigue performance of a hybrid transitional joint in an I-girder stiffener using DED-Arc AM46 steel from a material and detail perspective. High-cycle fatigue (HCF) tests were performed on machined/polished specimens extracted in horizontal and vertical directions relative to the welding beads. The obtained results were...

Stari konak manastira Bogovađa sazidan je 1858. god. u obliku ćiriličnog slova ,,P,,  dužine 31.50 m, širine do 11.60 m srednji brod, a paralelni brodovi su 21.00 m x 8.40 m. Ima 1/3 suteren visine 3.20 m i prizemlje visine 3.80 m. Zidan je u opeci bez ojačanja. Od dejstva zemljotresa su nastala značajna oštećenja na zidovima pri...

Trenutno važeći Evropski standardi propisuju minimalne kriterijume za serklaže u zidovima uokvirenim serklažima, dok se zahtevi u pogledu unutrašnjih sila u njima uglavnom eksplicitno ne određuju. U ovom radu predstavljena je metodologija bazirana na podacima iz numeričkih analiza usmerena ka racionalnom dimenzionisanju serklaža prema realni...
