This document discusses dynamic analysis of soil structure interaction on gravity dams. It first provides background on dynamic analysis and how the behavior of dams is influenced by foundation conditions. It then reviews literature showing that considering soil stiffness, mass, and soil-structure interaction leads to higher displacements and stresses in dams compared to models without these factors. The document outlines a methodology to model different soil types, analyze soil-structure interaction, and conduct dynamic analysis. It provides a time schedule and expected outcomes of discovering displacement based on soil-structure interaction and seismic response of the structure. Finally, it lists references on this topic.

1. dynamic ANALYSIS of soil structure interaction on gravity dam
25 October 2019 1
2. Introduction
• Dynamic analysis is the primary component in all types of
construction, usually in areas of high earthquake activity.
• Dam is the structure which is designed in such a way that its
own weight resist the external forces.
• The behaviour of the dam is greatly influenced by the
foundation conditions.

3. Literature
Author Year Title Findings
V. Swapnal 2015 Effect of Soil Structure Interaction on
Gravity Dam
•If soil stiffness and
mass of the soil is
considered the
displacement is
higher for the soil
structure interaction
compared to that of
without soil
structure interaction.
Berrabah et.al 2012 Dynamic Soil Structure Interaction
Study
•The case of the dam
with soil is more
conservative; it
develops more
displacement
amplitude and more
stresses than the
case of the dam
without soil.

Gravity Dam on Random Soil
• The natural

from this with
medium soil due to
difference in stiffens
