Question

Assuming the concrete below the neutral axis to be cracked, the shear stress across the depth of a singly reinforced rectangular beam section

• A. increases parabolically to the neutral axis and then drops abruptly to zero value
• B. increases parabolically to the neutral axis and then remains constant over the remaining depth
• C. increases linearly to the neutral axis and then remains constant up to the tension steel
• D. increases parabolically to the neutral axis and then remains constant up to the tension steel

Answer 1

The correct option is D increases parabolically to the neutral axis and then remains constant up to the tension steel

(d)
For cracked section,
Actual stress distribution
