Original Abstract
The paper deals with the influence of correlation length, of Gauss random field, and of yield strength of a hot-rolled I-beam under bending on the ultimate load carrying capacity limit state. Load carrying capacity is an output random quantity depending on input random imperfections. Latin Hypercube Sampling Method is used for sampling simulation. Load carrying capacity is computed by the programme ANSYS using shell finite elements and nonlinear computation methods. The nonlinear FEM computation model takes into consideration the effect of lateral-torsional buckling on the ultimate limit state.
Keywords
FEM, beam, shells, buckling, nonlinear analysis, imperfections, yield strength, random field.
