CFVR1425 - Axial+Shear checking according to EHE

check a reinforced concrete beam subjected to Axial force + Shear force according to EHE

A fixed beam which has a rectangular reinforced concrete section is subjected to an axial compression force of 300 N and a shear force of 500 N on the Y axis direction.
The aim of the example is to obtain the check criterion according to EHE.
