6.2.3 Members requiring design shear reinforcement

C6.2.3 Members requiring shear reinforcement. Non prestressed members

In ENV 1992-1-1 the Standard Method and the Variable Inclination Method were offered as design alternatives. The Standard Method, in spite of its acceptable accuracy, is from a physical point of view unsatisfactory, because the "concrete term" is purely empirical and hides the physical reality. This reality is, that a redistribution of forces occurs in the webs of shear reinforced concrete beams, resulting in strut inclinations smaller than 45°, Fig. 6.24.
