dcterms:description
Vliv počátečních imperfekcí na chování tenkostěnných ocelových nosníků je studován metodami citlivostní analýzy. Byly použity moderní numerické metody MKP: Euler Newton Raphsonovo řešení. Rovněž bylo uvedeno srovnání s experimenty. The influence of initial imperfections on the behaviour of a thin-walled girder welded of slender plate elements is analysed in the present paper. The experimentally determined girder load-bearing capacity value was analysed. The ultimate load test was computer modelled by theoretical analysis. In so doing, the girder was modelled, using the geometrically and materially nonlinear variant of the shell finite element method, by the ANSYS programme. The random influence of all initial imperfections was connsidered and the sensitivity analysis of the initial imperfections influence on the load-bearing capacity has been evaluated. In this way, it was found out which initial imperfections exhibited the greatest influence on the load-bearing capacity. The experimental research provides an idea about crack propagation in dependence on the number of loading cycles. According to experimental results for girders subjected to repeated loading in points A, B, C and Dhave been chosen in which fatigue crack initiati The influence of initial imperfections on the behaviour of a thin-walled girder welded of slender plate elements is analysed in the present paper.
