Verification of Rectangular Cross Section Made of Plain Concrete
The cross section is rectangular, loaded by the bending moment M, normal force P (applied in the cross section centroid) and by the shear force Vn.
The shear strength is provided by (Art. 22.5.4, Art. 9.3.5):
Strength of concrete cross section subject to the combination of bending moment and normal force is derived from the following expressions (Art. 22.5.3, Art. 9.3.5):
for compression side:
for tension side:
