Course Objectives:

• 1. To understand soil structure interaction.
• 2. To analyse the stress-strain behavior of soils
• 3. To estimate interaction parameters under static and dynamic conditions
• 4. To analyse the foundations resting on soil as beam-plate on elastic foundation

Course Outcomes

At the end of the course, student will be able to:

• 1. Apply different soil response models for specific problem based on the
