Sensitivity Analysis of the Effect of Initial Imperfections on the Stress State in the Crack-Prone Areas of Breathing Webs

Popis výsledku v původním jazyce

The objective of the paper is to analyse the influence of initial imperfections on the behaviour of thin-walled girders welded of slender plate elements. In parallel with experiments conducted in Prague, one of the ultimate load tests was computer modelled. In so doing, the girder was modelled, using the geometrically and materially non-linear variant of the shell finite element method, by the ANSYS program. Considering a random influence of all initial imperfections, a sensitivity analysis of the effecct of all imperfections on the load-carrying capacity of the girder was carried out. In this way, it was found out which initial imperfections exhibited the greatest influence on the load-carrying capacity. Based on observations made in the course of thePrague experiments, points A and B, where under repeated loads fatigue cracks occur most frequently, were chosen for a computer analysis of the stress state generated at the toes of the fillet welds connecting the slender web with the gi
