Abstract

Nosilne konstrukcije so zgrajene iz različnih konstrukcijskih elementov, ki jih v statiki glede na način prenašanja obremenitev delimo v tri glavne skupine. Izmed teh se bomo podrobneje posvetili palicam, za katere je značilno, da prenašajo le osne obremenitve. Cilj zaključne naloge je konstruirati palično konstrukcijo mostu in z metodo končnih elementov v programskem okolju ANSYS Mechanical APDL določiti notranje osne napetosti v palicah. Dobljene rezultate smo verificirali z analitično izračunanimi vrednostmi po metodi vozlišč in glede na izračunane maksimalne napetosti ustrezno vrednotili palice. Pokazali smo, da so napetosti tako natezno, kot tudi tlačno obremenjenih palic, znotraj dopustnih meja.

Secondary title: Analysis of truss structures using finite element method
Secondary abstract: The load-bearing structures are made of different structural elements, which are divided into three main groups based on the way they bear loads. Among these, we will focus in more detail on truss members, which can carry only axial loads. The aim of the final thesis is to construct a truss structure of a bridge and to determine the internal axial stresses in it%s bars using the finite element method in the ANSYS Mechanical APDL software environment. The obtained results were verified by manually calculated values using the method of joints. Based on the maximum stresses, the bars were appropriately evaluated. We have shown that the stresses of both the tensile and pressure-laden bars are within permissible limits.
