Design of Beams MCQ with answer and solution

A doubly reinforced RCC beam is recommended when

Solution

Concept

When to use compression steel

Step-by-step solution

1. If depth is restricted, a singly reinforced section cannot give the required moment. 2. Compression steel is added.

Explanation

Compression reinforcement increases the moment capacity without increasing depth.

Why the other options are wrong

Shear needs stirrups, not compression steel.

Shortcut

Restricted depth → doubly reinforced.

Correct answer: A) Depth of the beam is restricted
