Finite Element Analysis of Seismic Response of yielding system structu

Most of the structures (under ground and over ground structures) involve some type of structural element with direct contact with the ground. When the external forces, such as earthquakes, act on these systems, neither the structural displacements nor the ground displacements, are independent of each other. The process in which the response of the soil influences the motion of the structure and the motion of the structure influences the response of the soil is termed as soil-structure interaction (SSI).
