Engineering Model for the Vertical Shear Capacity of Composite Slabs with Additional Reinforcing Steel

Up to now, no independent model for the shear design of composite slabs under the consideration of the two types of longitudinal reinforcement – metal sheet and reinforcing steel – exists. Therefore, extensive investigations were conducted at Technische Universität Kaiserslautern. The research project was completed recently. A new engineering model, which was calibrated on tests, was developed. Furthermore, the engineering model was transferred into a design model. In this paper the experimental investigations are presented as well as the engineering model.
