Question

Shear strength of concrete in a reinforced concrete beam is a function of which of the following:

1. Compressive strength of concrete
2. Percentage of shear reinforcement
3. Percentage of longitudinal reinforcement in tension in the section
4. Percentage total longitudinal reinforcement in the section

Select the correct answer using the codes given below:

• A. 1, 2 and 4
• B. 1, 2 and 3
• C. Only 1 and 3
• D. Only 1 and 4

Answer 1

The correct option is C Only 1 and 3

(c) The design shear strength of concrete in RC beam depends upon grade of concrete i,e. compressive strength of concrete; percentage of longitudinal tension reinforcement; and axial compressive force.
