Question

Slenderness ratio is inversely proportional to __________

(a) Effective height

(b) Effective thickness

(c) Effective length

(d) Effective height and effective thickness

The question was asked in a national level competition.

My question comes from Load Bearing Walls in section Load Bearing Walls of Construction & Building Materials

Answer 1

The correct option is (b) Effective thickness

Explanation: Slenderness ratio depends on the effective length or height and effective thickness. It is directly proportional to the effective length or effective height, whichever is less. And, it is inversely proportional to the effective thickness of the wall.
