Structural Response of RC-Members in Case of Impulsive Loading. Failure Analysis in Bending and Shear,
Abstract
Beams and one-way slabs subjected to impulsive loading are analyzed with aid of a numerical model, which is kept as simple as posible, and which is sufficient powerful to simulate real beam response. Therefore the beam is schematized as a system of rigid sections and elasto-plastic hinges which can account for hysteresis. The equations which hold for this discrete model are presented. They are solved by use of the systems dynamics language Dynamo. In case of the application of an impulsive loading to a simply supported beam a very typical pattern of 'traveling' plastic hinges may occur, different to what is known from static loads. In case of the application of an explosive load to a beam with clamped ends, the similarity with static results is much greater. In the example of the flat roof of a traffic tunnel however, the shear failure criterion is extremely dominant, yielding strongly reduced allowable peak values of the explosive loads.
