Foundation Engineering

foundation design

Foundation is the low part of the structure which transmits the load of the structure to the ground. The foundation is a buried structure and we cannot see it directly as superstructure. This fact creates bias-ness in designer towards the superstructure which foundation remain given less importance. So, …
