Original Abstract

The main purpose of the presented paper is to give basis usable to increasing the reliability of designed structures. The article deals with an analysis of the influence of initial imperfection on stress and load-carrying capacity of a steel strut under axial compression. The influence of the initial imperfection on the observed output is quantified applying the so-called stochastic sensitivity analysis. Initial imperfections are defined by their statistic characteristics, obtained from experimental research in the Czech Republic. Real experiments are simulated on computers. The statistical evaluation of variables hard to measure, like stress, can be advantageously carried out. Basic types of stochastic sensitivity analysis are listed and the suitability of their application to the analysis of stability problems of steel structures is discussed. Results can be used for the specification of those input variables which should be, in production, checked with increased accuracy. For dominant variables, it is possible to aim at decreasing their variability, which is inevitably given by production inaccuracy. The numerical simulation method Monte Carlo is used in presented studies.
