Question

Effective length of a wall when it is supported by a buttress only at one end is __________

(a) 1.5L

(b) 1.0L

(c) 0.5L

(d) 2.0L

I have been asked this question in examination.

The origin of the question is Effective Length and Thickness of Wall in division Load Bearing Walls of Construction & Building Materials

Answer 1

Right choice is (a) 1.5L

To explain: Effective length of a wall when it is supported by a buttress only at one end is 1.5L where L is the actual length of the wall. In this case, the wall is free at the other end. The support can be provided by a cross-wall also instead of a buttress.
