Shear check

 

The shear check is commonly based on the theory of the concrete truss-model. In this theory a virtual truss-model is imagined in a concrete beam. This truss-model has a set of vertical (or slightly diagonal), horizontal and diagonal members. The vertical bars are considered to be the stirrups; the horizontal bars are the main reinforcement and the diagonal bars are the concrete struts. The check of biaxial shear is calculated according to preconditions in clause 6.2 in EN 1992-1-1.

There are the following assumptions:
