Abstract

The contribution deals with describing of two experimental approaches leading to assumption of modal parameters in a form of natural frequencies, mode shapes and damping of freely supported steel pipe. In the first approach, the model of the pipe was created in common way using planar elements. In the second one, the model of the pipe was simplified using line elements, which should lead to the increasing of time needed for realization of experimental investigation. The results obtained by both approaches as well as their pros and cons are described in the paper.
