Experiences from past earthquake disasters clearly shows that the ground motion was highly responsible for majority of property and life loss. Excessive damage was occurred to pile supported bridges, towers, chimneys, high rise structures, etc among the collapsed structures. A numerical study is carried out to understand the dynamic soil structure interaction of a high rise structure in a visco elastic half space in the presence of nearby pile supported structures. For understanding the seismic response of group of high rise structures supported on pile foundations a two dimensional study is carried. Framed structures which are assumed from the linear structures of different dynamic characteristics are supported on group of piles. Some studies related to group effect of structures supported on piles are considered like group of two identical structures, group of three identical structures and group of three different structures, secondly the effect of variability in structure height is considered like 5 storey structure, 10 storey structure and 15 storey structure and the third one in which the effect of variability in structure shape is considered. Above all case the effect of structure soil structure interaction on seismic response is compared with fixed base response.
