Abstract
V diplomski nalogi sem naredila stabilnostno analizo jeklene strehe športne dvorane v Stožicah. V uvodnem delu sem se ukvarjala z lokom razpona 10 m. Opazovala sem vpliv različnih vrst podpor (togo podprto, vrtljivo podprto), oblik enakomerno porazdeljene obtežbe, oblikovnega faktorja h/L (h – višina loka, L – razpon loka) ter velikosti in obliko vnesene nepopolnosti. Namen uvodnih analiz je predvsem spoznavanje s programoma Abaqus in Scia Engineer. Stabilnostna analiza jeklene strehe športne dvorane v Stožicah je narejena s programom Abaqus ter delno s programom Scia Engineer. Osredotočila sem se na globalno stabilnost – preskok celotnega sistema. Računala sem mejni obtežni faktor, s katerim še lahko pomnožimo različno obliko obtežbe s snegom, da bo konstrukcija še stabilna. Ker je najbolj neugodna porazdelitev obtežbe kopičenje snega, sem se osredotočila predvsem na ta primer ter na enakomerno porazdelitev snega. Opazovala sem deformiranje konstrukcije pred dosegom mejnega obtežnega faktorja ter po njem in za značilne točke strehe narisala diagrame obtežba – pomik (P-w). Kontrolirala sem kritične elemente konstrukcije glede na osno silo. Opazovala sem še vpliv amplitude nepopolnosti na končno nosilnost ter vpliv višine nakopičenega snega na manj obremenjeni strani strehe.

Title:Stability analysis of sports hall Stožice steel roof : graduation thesis
Abstract:
In my thesis, stability analysis of sports hall Stožice steel roof was made. In the first part the arch with span 10 m was computed. Different support types (roller, pin), load forms, factor h/L (h – heigth, L – span), amplitude and form of imperfections were watched. The purpose of this analysis was to become familiar with programs Abaqus and Scia Engineer. Stability analysis of sports hall Stozice steel roof was made with program Abaqus and some parts with program Scia Engineer. The focus was on the global stability of the roof – snap-through effect. I computed critical load propotional factor, with which we can multify different types of snow load, to assure that the construction is still stable. Since the unsymetric snow accomulation is the most negative, the most work was made with that case and with constant snow load. Deformations of roof before and after load proportional factor reached the critical value were monitoring and the graph Load – vertical displacement (P-w) was made for chosen points. Axial force and moments were also checked in critical elements.The amplitudes of imperfections and hight of accomulated snow load were watched.
