Abstract
For the modeling of reinforced concrete structures under quasi-static, dynamic and impulsive loading different approaches are commonly used within the analysis, such as the Single Degree Of Freedom (SDOF) approach, finite element methods using implicit or explicit methods and hydrocode simulations. The proposed paper sates the possibility for the description of the structural dynamic behavior of reinforced concrete using two different SDOF Method based on experimental shock tube tests on single-span reinforced concrete-slabs and analyses their applicability regarding plastic hinge formation. Furthermore studies on the effects of preloading for a representative structural element will be carried out, which allow for an indication of the influence of preload on the dynamic resistance of structural elements. This will help to analyse reinforced concrete from the quasi-static to the dynamic and impulsive domain of response at different loading rates under preloaded conditions.
