Abstract

• Geometrically and materially non-linear finite element model using solid finite elements • Introduction of initial random imperfections of a steel beam subjected to lateral-torsional buckling • Polynomial approximation of the load-carrying capacity (LCC) of a steel beam with imperfections subjected to bending • Simulation computational analysis of the LCC of steel beams with initial random imperfections • Statistical and sensitivity analysis of the random LCC with emphasis on design percentiles and reliability
