Abstract

The construction materials used in structural engineering possess more or less pronounced elastic properties. These elastic properties are responsible, at least in part, for the deformations of the components made from them. Depending on the type and nature of the component as well as the type and level of its loading, the deformations manifest themselves, for example, as elongations and/or deflections. A distinction must be made between deformations due to static resting load and those due to dynamic load. In the latter case, the deformations are also time-dependent in short-term tests. They can be described in a suitable manner by the vibration behavior of the component or test specimen.
