In this paper, the influence of bridge expansion length on the distribution of additional temperature stresses in continuously welded rails is investigated. Using a representative railway viaduct as a case study, the effects of thermal interaction between the track and the bridge are analyzed. The research focuses on the design phase, particularly ...

The construction sector plays an important role in economic development but is highly sensitive to financial constraints during project implementation. While existing studies mainly focus on the sources of financing, less attention has been paid to the availability and timing of financial flows throughout the project lifecycle. Delays in financial ...

Rural primary schools within the Municipality of Lazarevac represent a significant portion of the public building stock. Most of the buildings are single-storey with load-bearing masonry systems, built in the second half of the 20th century according to the technical regulations of that period, which did not seismic resistance, durability, and ener...

The use of finely ground waste cathode ray tube (CRT) glass as a partial replacement for cement directly links the principles of circular economy with the reduction of carbon dioxide emissions. Instead of ending up in landfills, glass is returned to the production cycle as a pozzolanic material, reducing the need for extracting natural resources an...

This paper presents the design of a reinforced concrete arch bridge over the Đetinja River canyon, part of the Užice bypass route in Serbia. The 292 m long structure features a main arch span of 162 m with a rise of 23,6 m (rise-to-span ratio 1/6,86), placing the deck approximately 90 m above river level. The rationale for selecting a relatively sh...

This study proposes an artificial intelligence-based framework for financial risk assessment and cost prediction in construction experiments, focusing on steel hall assembly processes. Construction experiments involving real-time monitoring technologies are associated with significant financial uncertainty. Proposed framework combines cost modeling...

Rekonstrukcija objekta metalurgije, radi proširenja proizvodnog kapaciteta, nekad zahteva ojačanje, rušenje i građenje čelične i/ili armirano-betonske konstrukcije. Rušenje konstrukcije je rizičan posao, koji zahteva dosta iskustva. Kinesko preduzeće “Ciđin” (ZiJin) otpočelo je rekonstrukciju Topionice i Rafinacije ...

Prema EN 1993-1-9, pri verifikaciji zamor proračunske situacije, svi relevantni efekti povećanja napona u svim karakterističnim konstrukcionim detaljima moraju se uzeti u obzir, bez obzira na izabranu metodu proračunskog napona. Metode za verifikaciju graničnog stanja na zamor su metoda nominalnog napona, metoda napona u „vrućim-tačakama&ldq...

Major infrastructure failures rarely originate from a single defect, but emerge when deterioration, unfavorable load paths, limited redundancy, increasing operational demand, and incomplete knowledge interact. This paper synthesizes forensic and life-cycle evidence from two collapses: the 2018 Polcevera Viaduct in Genoa and the 2021 Champlain Tower...
