Stability of roof trusses stiffened by corrugated sheets
The present parametric study is devoted to the stability analysis of a set of trusses stiffened by decking of corrugated steel sheets. For different parameters of corrugated sheets the critical loading of the roof is calculated. In the parametrical analysis the threshold bracing condition of the roof is obtained. Then the geometrically non-linear analysis of trusses braced by corrugated sheets was conducted. As a results of non-linear analysis the forces in roof corrugated sheets was calculated and compared with requirements existing in the design codes both in Polish Code and Eurocode.
