Abstract
The advantages of composite structures can only be utilized if joints between steel and concrete meet economical and technical demands. In the area of these joints large forces often have to be transferred in a localized concentrated area of concrete. Bearing points of bridges or foundations of columns are typical applications for this purpose. Especially for these cases the bearing capacity of the joints determined by the design standard is very conservative due to a possible concrete edge failure. Furthermore the beneficial impact of existing reinforcement or superimposed loads on the load-bearing behavior isn’t considered in current standards. However, the bearing capacity of the concrete is increased by a superimposed load due to the compression of the concrete and additional shear capacity based on the friction between steel plate and concrete. Innovative solutions for this areas could be developed by considering these aspects.
Within this research project a practical design concept for steel-to-concrete joints with superimposed loads will be developed considering edge influences, effects due to friction and existing reinforcement. Experimental and numerical investigations on anchor plates with headed studs will be conducted and used to verify the design model.
