The diagonal tension failure in a concrete beam occurs due to
A. Large shear force and less bending moment
B. Large bending moment and less shear force
C. Equal shear force and bending moment
D. None of these
Please scroll down to see the correct answer and solution guide.
Right Answer is: A
SOLUTION
It is diagonal tension which is responsible for crack formation near the supports. The shear force is quite high and the bending stresses are very small. Hence principal tensile stress is nearly equal to shear stress.
For such a failure to happen τ ≫ σ.
