Dynamische Systemantwort des Timoshenko-Balkens unter Impulseinwirkung aus Detonation

Column constructions are designed to safely transfer vertical loads into the ground. Hence additional horizontal loading caused by accidental loading due to explosion constitute a major challenge. The determination of the dynamic system response at variable axial loading is required to identify the dynamic effects with adequate accuracy, to understand the mechanisms and to derive the design state. It is of importance to choose a suitable beam theory in combination with an efficient solution strategy. Herein, the modal analysis with an extension for continuous systems is applied on basis of the Timoshenko beam theory. The complete solution strategy is presented, investigated, compared with other selected strategies and discussed herein.
