Abstract

U okviru rada analiziraju se spregnuti gredni mostovi sa “I“ nosačima na autocestama i brzim cestama uz primjenu Modela opterećenja 3 u odnosu na primjenu Modela opterećenja 1. Izrađeno je četrdeset modela spregnutih mostova različitih raspona, poprečnih presjeka i širina mostova ovisno radi li se o mostovima na autocesti ili brzoj cesti. Rad se sastoji od dva dijela. U prvom, teoretskom, dijelu opisani su tipovi spregnutih mostova, navedene su njihove prednosti i mane, dane su smjernice za oblikovanje poprečnih presjeka i opisani su modeli prometnih opterećenja. Drugi dio rada bavi se analizom i dimenzioniranjem spregnutih mostova. Napravljena je usporedba momenata savijanja za Model opterećenja 1 (LM1) i kombinaciju Modela opterećenja 1 i Modela opterećenja 3 (LM3) u kojoj su prikazani i mjerodavni glavni nosači za dimenzioniranje. Uspoređene su i dimenzije glavnih nosača za mostove na autocesti i brzoj cesti ovisno o opterećenju LM1 i LM3 te je prikazana količina materijala. Na kraju rada dan je prijedlog dimenzija “I“ nosača na autocestama i brzim cestama prema napravljenim analizama.

Abstract (english)

Within this paper, composite bridges with "I" girders on highways and expressways are analyzed with the application of Load Model 3 in relation to Load Model 1. Forty models of composite bridges of different spans, cross-sections and bridge widths were made depending on whether they are highway or expressway bridges. The paper consists of two parts. In the first, theoretical part, the types of composite bridges are described, their advantages and disadvantages are listed, guidelines for the design of cross-sections are given, and models of traffic loads are described. The second part of the work deals with the analysis and sizing of composite bridges. A comparison of the bending moments for Load Model 1 (LM1) and the combination of Load Model 1 and Load Model 3 (LM3) was made, in which the relevant main girders for dimensioning are also shown. The dimensions of the main girders for highway and expressway bridges were compared depending on the LM1 load and LM3 load, and the steel consumption was shown. In conclusion, a proposal for the dimensions of "I" girders on highways and expressways is given according to the analysis.
