Optimizing the shear design of slabs

A significant amount of the used concrete volume is applied to slab structures where shear design is often determinative of the dimensioning. Since applying shear reinforcement to slabs is elaborate, structural engineers intend to omit shear reinforcement in in-situ concrete slabs in construction practice. The current shear design approach for components without shear reinforcement according to EC2 is semi-empirical and was calibrated using a database of shear tests on simply supported single-span beams under concentrated loads. Therefore, capacity increasing influences due to more realistic
