(d) 1.50H

The question was asked in examination.

This interesting question is from Effective Height of Wall in chapter Load Bearing Walls of Construction & Building Materials

Answer 1

Correct answer is (d) 1.50H

For explanation I would say: The effective height of a wall of actual height H partially restrained at the bottom and having no lateral support at the top is 1.50H. This is also true if it has no rotational support at the top.
