Question

The section in which concrete is not fully stressed to its maximum permissible value while steel reaches its maximum value, is called ___

• A. Under reinforced section
• B. Critical section
• C. Over reinforced section
• D. Balanced section

Hint:

In reinforced concrete design, aim for an under-reinforced section for safe failure behavior where concrete fails first, providing warning.

Answer 1

The Correct Option is A

In an under-reinforced section, the concrete is not stressed to its maximum permissible value, while the steel reinforcement reaches its maximum value. This is a desirable condition in design because it ensures that the concrete will fail before the steel, providing a warning before the beam fails. Hence, the correct answer is "Under reinforced section".
