JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

To understand the effect of earthquake on soil structures and to design

earthquake resistant geotechnical structures.

Course Outcome

Able to understand the behavior of ground during the earthquakes, so that

geotechnical structures can be designed to resist/ sustain the earthquake loading.
