Statistical and sensitivity analysis within the elaboration of steel plated girder resistance

Original language description

The objective of thr paper is to analyse the influence of initial imperfections on the behaviour of thin-walled girders welded of slender plate elements. The girder wasmodelled, using the geometrically and materially non-linear variant of the shell finite element method, by the ANSYS program. The ultimate static load-carrying capacity and the state of stress were considered as the output analysed quantities. The influence of the variability of initial imperfections on the variability of ultimate staticload-carrying capacity and on the variability of the state of stress studies was calculated by sensitivity analysis. The sensitivity analysis was evaluated on a computer by appling the numerical simulation LHS method and statistical characteristics evaluated, based on the experiments. Real tests of girders with random initial imperfections the occurrence frequency of which is equivalent to experimental results are simulated numerically. In each LHS method run, both load-carrying capacity
