The width of a strip foundation supporting a load of 35 KN/m on a soil with a loadbearing capacity of 120 KN/m² and having a factor of safety of 1.5, should be A) 194mm B) 292mm C) 343mm D) 437mm E) 515mm

Question

Quizplus · Accepted Answer

To find the width of the strip foundation, use the formula: Width = Load / (Safe bearing capacity). The safe bearing capacity is the loadbearing capacity divided by the factor of safety: 120 KN/m² / 1.5 = 80 KN/m². Therefore, Width = 35 KN/m / 80 KN/m² = 0.4375 m or 437 mm.
