Seismic Analysis of Pile Group with Different Variations in Dimensions and Parameters

Abstract

As per demand of current construction many project are running such as metro construction, bridges, tall building, industries, etc. In such type of construction where the soil bearing capacity (SBC) is very low it is necessary to provide pile foundation. Dynamic analysis is also necessary to be carried out for different pile group for earthquake. The stress resting action increases with the group action of piles. In the present study, describe about pile group, modeling of four piles and eight pile groups were done taking space between them as 2.5D and 3D, where D is the dia. 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 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.
