Question

_______ occurs due to various reasons such as unequal distribution of load on the foundations, varying bearing power of the sub soil, eccentricity of the load, etc.

(a) Unequal settlement of the sub-soil

(b) Unequal settlement of the masonry

(c) Horizontal movement of the earth

(d) Withdrawal of moisture from the sub-soil

This question was addressed to me during an internship interview.

The query is from Foundations topic in section Foundations of Construction & Building Materials

Answer 1

Correct choice is (a) Unequal settlement of the sub-soil

For explanation: Due to unequal settlement of the sub-soil, the cracks are formed in the buildings, which in future, leads to serious defects. To prevent such failure, the foundations should rest on the rock or hard murum.
