ANCHOR PLATES WITH WELDED STUDS ON BASIS OF THE COMPONENT METHOD

摘要

Anchor plates are used to transfer loads between steel and concrete structures. Based on two test series of reinforced concrete specimens with anchor plates under shear and tension forces carried out by the Institute of Structural Design at the University of Stuttgart a first mechanical model has been developed describing the load-carrying capacity of anchor plates with welded studs in reinforced concrete elements. Within the scope of this first mechanical model only the maximum strength was considered. The stiffness and the ductility were not taken into account due to a clear inner load distribution, e.g. as there is only one type of fastener for shear load transfer. Supplementary reinforcement decisively influences the load-carrying capacity and the ductility of these steel-to-concrete joints. The mechanical model based on the component method offers transparency of load distribution and applicability to various situations.
