A. providing buttresses at certain intervals
B. providing a deeper foundation
C. using a richer mortar
D. using stronger bricks
Assertion A : From consideration of structural soundness and economy of design, most codes control the maximum slenderness ratio of masonry walls and columns. Reason R : By controlling the maximum slenderness ratio, failure is by excessive stress and not by buckling.?
