1. COMPRESSION FIELD THEORY FOR SHEAR STRENGTH IN CONCRETE
8. ASSUMPTIONS ABOUT SHEAR STRENGTH The beam fails when the concrete in the struts reaches its crushing strength.
At failure, the beam has shear cracks and the cracks have opened
This would cause the stirrups to yield.
The compressive strength of concrete between the shear cracks (struts) is less than fc.
