The construction industry is one of the largest consumers of non-renewable natural resources and a significant source of CO₂ emissions, which underscores the need to develop more sustainable materials that can reduce its negative environmental impact. In order to meet the requirements of the modern circular economy, this study investigates the pote...

Obavezna primena evrokodova u Republici Srbiji uvedena je relativno skoro, što je u pojedinim slučajevima nametnulo izazove, jer su razlike u odnosu na dosadašnju praksu znatne. Priprema nove generacije evrokodova trenutno je u završnoj fazi. Kako će u bliskoj budućnosti nova generacija evrokodova biti objavljena i obavezujuća ...

Stari savski most bio je ratni most u centru Beograd, izgrađen 1942. godine od strane Nemačkog Rajha, radi održavanja veze preko reke Sava, nakon rušenja Mosta kralja Aleksandra. Prvobitno namenjen kao privremena konstrukcija za vojni transport, služio je kao glavni tramvajski most do 2020. godine. Uzimajući u obzir stanje čelične konstrukci...

Projekat Novog savskog mosta započet je 2020. godine kao Design-Build ugovor između Republike Srbije i kineske kompanije PowerChina International, za izgradnju novog, modernog mosta većeg kapaciteta na istom mestu gde je bio Stari savski most. Završne faze projekta mosta su urađene od strane konzorcijuma sastavljenog od kompanija: Millennium...

The increasing availability of experimental data in civil engineering has created new opportunities for the application of artificial intelligence techniques in structural engineering research. Machine learning approaches provide powerful tools for identifying complex relationships between material composition and mechanical properties. In this stu...

The primary parking structure serving O’Hare International Airport was opened for use in 1973 with 10,000 parking spaces and over 240,000 square meters of supported slabs. The six-story concrete structure was primarily reinforced using button-head post-tensioning. A condition assessment was performed in January of 2018 and identified structur...

This paper presents a 2D nonlinear analysis of the load-carrying capacity of unbraced and concentrically braced steel frames subjected to lateral loading. The study was conducted using the incremental ("step-by-step") analytical method and finite element analysis. The effects of material and geometric nonlinearities, axial force, and brace cross-se...

During incremental bridge launching, patch loading is transferred through launching shoes. In this case, rotation of the loading block about the longitudinal axis of the girder is usually restrained. However, in some practical applications, such as crane runway girders subjected to wheel loads, the “loading block” is free to rotate. The...

A comparative analysis was conducted on reinforced concrete frame structures designed according to the first and second generations of Eurocode 8, focusing on the DCM and the DC3 ductility classes. The results show similar global behaviour and identical seismic forces, but differ in required ductility and in the amount of longitudinal and transvers...

This paper presents the full-scale static tensile factory acceptance testing of the OVM.ST15-47 parallel-strand hanger system intended for installation on the New Sava Bridge in Belgrade, Serbia. Each tested hanger assembly consisted of 47 seven-wire prestressing strands, with a nominal tensile strength of 1,860 MPa and a nominal cross-sectional ar...
