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...

This paper presents a parametric numerical study on the influence of the number of storeys and number of bays on the structural response of planar reinforced concrete frame systems. Numerical models with one to six storeys and bays were analyzed under symmetric and asymmetric loading conditions. The frames were subjected to uniformly distributed lo...

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 ...

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 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...

Projektovanje sanacije postojećih TBM tunela zahteva proveru stvarnog stanja konstrukcije, a ne oslanjanje isključivo na pretpostavke prvobitnog projekta. U radu je prikazan objedinjeni postupak koji obuhvata pregled dokumentacije, vizuelni pregled, geološka, geotehnička i hidrogeološka istraživanja, ispitivanje betonskih kernova i nu...

U radu je prikazan razvoj i validacija numeričkog modela željezničkog vijadukta na km 117+155 na pruzi Novi Sad–Subotica primjenom rezultata dinamičkog probnog opterećenja. Analiza je obuhvatila armiranobetonske prednapregnute sandučaste raspone dužine 23,5 m i 31,5 m. Numerički model razvijen je u programu MIDAS Civil, pri čemu je analiziran...

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...

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...
