Description
| - 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 depend 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 plastic areas in its boundary elements. Thee 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. It is expected shear predominating for short span girder and local shear with global bending for long one. To solve the problem by means of FEA, the program system ANSYS was used. The thin-walled profile geometry was modelled by a four-node shell element which makes it possible to solve physical and geometr

- Chování konstrukce sestavené z ocelových tenkostěnných prvků je silně ovlivněno tvarem, který má konstrukce před zahájením zatěžování. Popsaný článek se zabývá vlivem počátečního tvaru zakřivení stojiny na hodnoty napětív oblasti vzniku trhlin. Je provedena numerická studie pomocí programového systému ANSYS metodou konečných prvků.
