As per demand of current construction many projects are running such as metro construction, bridges, tall building, and industries, etc. In such type of construction where the soil bearing capacity (SBC) is very low it is necessary to provide pile foundation. Conduction of dynamic analysis is for different pile group for earthquake. The stress resting action increases with the group action of piles. Present study describes about pile group, modeling of four piles and eight pile groups taking

... ce between them as 2.5D and 3D, where D is the diameter of the pile. Diameter of four pile group is 0.6 and diameter of eight pile group is 0.4, shape chosen to arrange the pile group are Rectangle, Square, Diamond and Staggered. The analysis of different shape pile groups has been done using the response spectrum method based using STAAD Pro. Parameters such as displacement, shear force (SF) and bending moment (BM) were taken in consideration for pile group analysis. Pile cap is analyzed for bending moment in 'y' and 'z' direction.
