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.
