Analiza sovprežnega nosilca preko dveh polj : diplomska naloga

Toporiš, Matej (author), Može, Primož (mentor)

V diplomski nalogi je obravnavan sovprežni nosilec jeklo-beton preko dveh polj, ki je del stropne konstrukcije v stavbi. Obravnavana je faza montaže, ko je nosilec v času betoniranja nepodprt in ko je nosilec v času betoniranja podprt na polovici razpona. V končnem stanju je pri kontroli mejnega stanja nosilnosti narejena plastična in elastična analiza nosilnosti prereza, pri slednji z upoštevanjem obeh stanj v fazi montaže. Notranje sile so izračunane z linearno elastično globalno analizo. Naloga zajema problematiko prisotnosti negativnih upogibnih momentov v sovprežnem nosilcu, katerim je pri dimenzioniranju potrebno posvetiti posebno pozornost. Pri kontroli mejnega stanja uporabnosti je narejena analiza pomikov z upoštevanjem obeh stanj v fazi montaže.

• Title: Analysis of composite beam over two spans

Abstract

The graduation thesis deals with a steel-concrete composite beam over two spans, being part of the floor structure of a buildnig. The following two scenarios examined at the construction stage during concreting: the beam is un- ropped, the beam is propped in the mid-span. The elastic and plastic analysis of the bending resistance of the composite beam, performed considering both construction stages. Internal forces have been calculated using the linear elastic global analysis. Furthermore, the thesis covers the presence of negative bending moments in the composite beam, which need to be paid particular attention in the design stage. The deflections were analysed in the serviceability limit state, taking into account both stages.
