Solar panels (SPs) are designed to withstand wind-induced loading, characterised by varying wind speeds and directions, as well as high turbulence. This paper examines force coefficient statistics—mean, standard deviation, 3-s gust and peak values—on an isolated SP model, using data from an experimental campaign conducted in the atmosph...

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 ...

U okviru ovog rada na jednostavan i pregledan način, kroz konkretan primer, prikazano je poređenje seizmičkog proračuna primenom važećeg i nacrta novog seta Evrokodova 2027, kako bi se jasno uočile izmene u projektovanju i njihov stvarni uticaj na obim proračuna i na krajnje rezultate dimenzionisanja. Ovakvo poređenje može biti korisno u upoznavanj...

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...

This study presents a probabilistic assessment of an existing four-span reinforced concrete slab bridge, considering the stochastic variations of concrete strength and the yield strength of reinforcement steel. Although Eurocode permits probabilistic assessment of existing bridges, it provides limited practical guidance. Bending and shear limit-sta...

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...

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 ...

The sustainable rehabilitation of existing reinforced concrete railway bridges is gaining importance as transportation infrastructure approaches the end of its original design life. Reusing existing concrete substructures instead of complete replacement offers substantial environmental and economic benefits but requires robust assessment and target...
