Abstrakt
This work deals with an analysis of isotropic or orthotropic girders subjected to transient dynamic loads. The duration of dynamic loading was assumed to be equal to a period of the natural fundamental flexural vibrations of a structure under analysis. Numerical calculations were performed with the finite element method using ANSYS® 11.0 software. The results of computations were presented as maximum angle of the rotation of the girder in a function of the dynamic load factor, DLF (the ratio of pulse loading amplitude to static critical load). In study it has been taken into account apart from the elastic–plastic range of material with isotropic hardening as well as the strain rate effect described by Perzyna model.
