Abstract
U radu je prikazana analiza spregnutih mostova s otvorenim presjecima za raspone od 40, 50 i 60 metara. Za svaki od raspona mogući presjeci sadrže različite tipove i broj ˝I˝ nosača, tj. za svaki raspon analizirana je varijanta s četiri glavna nosača s konstantom debljinom kolničke ploče, te s dva glavna nosača s kolničkom pločom s vutama. Analiza se provodi na modelima bez podupiranja gdje se spregnuti presjek aktivira nakon očvršćivanja betonske ploče i na modelima s podupiranjem pomoću privremenih oslonaca u trećinama raspona čime se postiže da se težina i čelika i betona preuzima spregnutim presjekom. Za sve modele napravljena je analiza i dimenzioniranje na trajna i prometna opterećenja, te na nejednoliku temperaturu, i tako je određena količina čelika prema graničnim stanjima. Promjena količina čelika za pojedine raspone i broj nosača ovisno o načinu gradnje uspoređena je pomoću dijagrama. Zaključno je dan komentar koji je od spregnutih presjeka je najpovoljniji ovisno o duljini raspona mosta.
Abstract (english)
The paper presents the analysis of composite bridges with open cross sections for spans of 40, 50 and 60 meters. For each of the spans, the possible cross sections include different types and numbers of "I" girders, i.e., for each span, a variant with four main girders with constant deck plate thickness and with two main girders with variable deck plate thickness was analyzed. The analysis was performed on unsupported models, where the composite section is activated after the concrete slab has cured, and on models supported by temporary supports in one-third of the span, so that the weight of both the steel and the concrete is delivered to the composite section. All models were analyzed and designed for permanent and traffic loads and for non-uniform temperature, and thus the amount of steel was determined according to the limit states. The change in steel quantity for different spans and number of girders was compared depending on the construction method graphically. Finally, a conclusion was made as to which of the composite cross sections is most favorable depending on the length of the bridge span.
