6.2.3.3. Members reinforced in shear with loads near to supports

Similar to members without shear reinforcement, in members with shear reinforcement the load bearing capacity is increased for loads near to supports. In the Standard Method, as formulated in ENV 1992-1-1 this was taken into account by multiplying the "concrete term", with a factor (2d/x). However, the Variable Inclination Method not containing a concrete term, it was introduced here for x/d < 2. The formulation for this case is then

The transmission of forces occurs according to Figure6.36.
