Description

The shear force resistance VRd, c without computational shear force reinforcement according to 6.2.2, EN 1992-1-1 [1] or 10.3.3, DIN 1045-1 [2] is calculated depending on the longitudinal reinforcement ratio. If the required longitudinal reinforcement from the bending design is used for the calculation of VRd, c, this leads to an underestimation of the shear force resistance without shear reinforcement in the vicinity of hinged end supports. In contrast to the shear force, the required bending reinforcement decreases in the direction of the support. In addition, the actually inserted longitudinal reinforcement usually deviates significantly from the required bending reinforcement in the end support area (for example, in the case of non -staggered beam reinforcement).
