Improved design models as against EC 2

Increase in the load-bearing capacity
of shear stud assemblies

A purposefully applied supplementary reinforcement can considerably increase the load-bearing capacity of fastenings embedded in concrete under tension load (mode of failure: concrete cone failure) and under shear load (mode of failure: concrete edge failure).

The design approaches for these applications are defined in EN 1992-4 [1]. Comparisons with latest test findings show that the approaches according to [1] in particular for minor anchorage depths (tension) or edge distances (shear) are generally very conservative. In case of strong supplementary reinforcement, the computed capacities in...
