[en] A typical constructional solution for the connection between steel and concrete load bearing elements in highrise- as well as multi-storey-buildings is the anchor plate in steel. A research project deals with the numerical simulation of the load flux between anchor plate, headed shear studs and concrete. Most existing solutions in narrow constructions are dissatisfying in the point of using and analyzing the reinforcement effects. For crack propagation detailed concrete elements with 3d-nonlinear material properties are used. This includes tension and compression capabilities to simulate crack initiation and local failure behavior of the concrete. To cover structural nonlinearities the contact between steel and concrete is considered. The results in form of load flux and crack pattern are validated by comparisons to test results. The numerical simulation will help in optimizing the ratio and position of the reinforcement.
