Nosilnost hladno oblikovanih jeklenih upogibnih nosilcev : diplomska naloga

Likovič, Ana (author), Može, Primož (mentor)

V diplomski nalogi obravnavam nosilnost hladno oblikovanih jeklenih upogibnih nosilcev. V prvem delu opišem karakteristike, proizvodnjo in možne porušitve hladno oblikovanih jeklenih prerezov ter njihovo obnašanje na upogibno obtežbo. Nato predstavim primer uporabe tovrstnih prerezov, in sicer detajl lega-pločevina na strehi in vpliv podpiranja pločevine na hladno oblikovani prerez. V drugem delu predstavim izračun kontrol prereza in nosilca (hladno oblikovanega Z profila) na strehi v naklonu, pri tem pa je spodnja pasnica pritrjena na primarni nosilec, zgornja pa na pločevino.

• Title: Bearing strength of cold-formed steel bending beams : Graduation thesis

Abstract

This thesis focuses on design of cold-formed steel beams. In the first part, the characteristics, manufacturing and possible failures of cold-formed steel elements and their behaviour under the influence of bending moment are described. Then, an example of the design of Z-purlin, where the roof sheeting provides lateral support to the purlin is demonstrated.

• Keywords: Purlins, sheeting, bending, lateral - torsional buckling
