By Prof. B. K. Maheshwari | IIT Roorkee

Learners enrolled: 1498

ABOUT THE COURSE :
The course covers various types of foundations, required soil investigations, soil parameters, and codes of practice. Design considerations for seismic resistant design of foundations. The course will focus on techniques of design of foundations so that it does not fail during earthquakes. This will cover both shallow and deep foundations. Major focus will be on the design of deep foundations for lateral loads.
