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...

Arheološka istraživanja Zapadnog podgrađa tvrđave Golubački grad otkrila su niz objekata i nalaza iz različitih epoha koje je bilo neophodno adekvatno pripremiti, adaptirati i sanirati, kako bi se obezbedila njihova trajnost, sigurnost i dostupnost posetiocima. U ovom radu je predstavljena sanacija objekata Rimske kuće i Turskog hamama, koja...

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 analysis of consolidation settlement and consolidation time due to the construction of a road embankment on the Kratovska Stena–Lučani section. The study was performed for three representative sections between bridge structures, considering different embankment heights and subsoil improvement options. The analysed cases...

U radu je prikazana uporedna analiza efikasnosti različitih vrsta premaza namenjenih zaštiti armiranobetonskih konstrukcija od karbonatizacije. Rezultati su zasnovani na seriji laboratorijskih ispitivanja uzoraka betona izloženih ubrzanoj karbonatizaciji, sprovedenih u skladu sa standardom SRPS EN 12390-12:2010, Ispitivanje očvrslog betona &...

This paper analyses the seismic behaviour of a RC building with a tunnel structural system under seismic loading. This system is increasingly used in modern construction due to spatial rigidity and rapid construction; however, strong earthquakes, such as the one in Türkiye in 2023, have shown that even such buildings can sustain significant da...

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...
