摘要
Until now there is no generally accepted mechanically justified design concept for the shear force bearing capacity of reinforced concrete slabs without shear reinforcement. To deliver a contribution for a better understanding of the shear force resistance, first trials were carried out at the Technical University of Kaiserslautern. In these tests the individual carrying parts were switched off in intended sequence. For this purpose, experiments were carried out with a displaced compression zone and with a switched off crack's aggregate interlock and eliminated dowel action of the longitudinal reinforcement [1]. The influence of the individual carrying parts to the total capacity could be visualized and verified by the recalculation of tests with voided flat slabs and installation slabs applying an existing mechanically justified calculation model following Gortz [2, 3].
