An earthquake occurs in the form of seismic waves due to sudden release of energy and results inground shaking.
During earthquake, seismic waves propagate through the soil which results in structural damage due to movements within the
earth’s crust. It impacts the behavior of interactionof components like building, foundation, underlying soils and also overall
system behavior. Whenearthquake occurs, the behavior of a building depends on distribution of mass, strength and stiffness.
Generally, the buildings are subjected to various types of forces throughout theirexistence. The forces can be static forces
due to dead and live loads and dynamic forces due to earthquake. In this study, the analysis is carried out for seismic response of
