Design of Beams MCQ with answer and solution

Concept

Prevention of web buckling

Step-by-step solution

1. Thin webs of deep beams may buckle under compressive stresses from shear or concentrated loads. 2. Stiffeners (vertical or horizontal) are welded to the web to increase its stability.

Explanation

Providing stiffeners (load bearing, intermediate transverse or longitudinal) is the standard way to prevent web buckling without making the web thicker.

Shortcut

Web buckling → stiffeners.

Common mistake

Choosing a thicker flange.
