Analiza przekroju poprzecznego z betonu niezbrojonego
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. 22.5.5, Art. 14.5.5.1):
Strength of concrete cross-section subject to the combination of bending moment and normal force is derived from the following expressions (Art. 21.2, Art. 14.5.2-4):
for compression side:
where:
for tension side:
where:
