Influence of material and geometric property statistics on the random buckling resistance of steel bisymmetric rolled double-tee section members under compression

The buckling resistance of steel elements in compression was evaluated in this paper. Members were made of bisymmetric double-tee rolled sections of narrow and wide flanges. The effects of residual stresses and geometric bow imperfections is not taken into account. The randomness of cross-section properties and mechanical properties of steel is taken into consideration. A number of Monte Carlo simulations of the random buckling resistance of steel elements in compression were performed taking into consideration the contemporary Polish and European statistical data. Conclusions and practical recommendations are presented with reference to PN-EN 1993-1-1:2006.
