Originální abstrakt

The objective of the paper is to analyze the influence of initial imperfections on the behavior of thin-walled girders welded of slender plate elements. In parallel with experiments conducted in Prague, one of the ultimate load tests was computer modeled. In so doing, the girder was modeled, using the geometrically and materially non-linear variant of the shell finite element method, by the ANSYS program. The shape changing during loading proces is often accompanying with sudden snap through i. e. rapid curvature change. For numerical description of these phenomenon is necessary to take into account an influence of inertial forces. It was carrying out full transient analyses of state with considering geometric and material non-linearity.
