Verification of rectangular cross-sections made from plain concrete
Verification of rectangular cross-sections made from plain concrete
The cross-section is rectangular, loaded by the bending moment M, normal force N (applied in the cross-section centroid) and by the shear force Q. The cross-section bearing capacity subjected to bending moment is given by:
The shear strength is provided by:
Strength of concrete cross-section subject to the combination of bending moment and normal force is derived from the following expressions depending on the normal force eccentricity e:
for:
