The width (B) of foundation of a masonry wall of thickness "t" directly resting on foundation block should be :

(Where, W = total load per metre (kN/m)

p₀ = safe bearing capacity of soil (kN/m²)

x = cantilever projection of foundation block from consideration of Bending moment.)

Answer 1

Concept:

Total load per meter on foundation (kN/m) = W kN

Safe bearing capacity of soil = p_o kN/m²

qImage6536293b9399acdfbc67d94d

Area required for foundation (A) = \(Total\, load\over Safe\,bearing\, capacity\, of\, soil\)

\(B\times 1={W\over p_o}\)

\(B={W\over p_o}\)

OR B = 3t (max of both the given values)

Hence option (3) is the correct answer.
