For a beam, the critical section for shear as per IS 456 is located:
RCCRCCMEDIUM
Choose the correct answer
A
At the centre of span
B
At the face of support
C
At distance d (effective depth) from the face of support
D
At L/4 from support
Correct Answer
C. At distance d (effective depth) from the face of support
Why is this the answer?
IS 456 Cl. 22.6.2: Critical section for shear is at a distance d (effective depth) from the face of support. This is because inclined compression struts carry shear near supports, so failure does not occur right at the face. Within d from support, the strut-and-tie mechanism is active.
