Eigen mode initial imperfection influence on behaviour of thin-walled systems
Original language description
The article deals with initial imperfection shape similar to first eigen mode buckling of thin-walled structures, i.e. systems made of slender plate elements. It was found out that initial imperfections exhibited the greatest influence on stress state incrack-prone areas and deflection. The behaviour of steel girders is substantially affected by the buckling of the girder web, which for the kind of loading considered, is characterized by a diagonal buckled pattern the width and inclination of which deppend on the rigidity of the peripheral elements of the web, i.e. of the flanges and stiffeners. When the loading is quasi-constant, the failure mechanism consists of a diagonal plastic band in the web sheet and a system of more or less developed plasticareas in its boundary elements. The problem will be investigated on the girder which has two and four square web panels and is loaded at its mid-span by a point load; hence, the web panels are subjected to combined shear and bending.

Vliv počáteční imperfekce ve vlastním tvaru ztráty stability na chování tenkostěnných nosníků
Czech description
Počáteční imperfekce má velký vliv na chování tenkostěnných ocelových nosníků. Byl uvažován vlastní tvar ztráty stability lineárního řešení. Tento tvar byl užit jako počáteční tvar při výpočtu geometricky nelineárního chování konstrukce.
