The structure is presumed to be situated in seismic Zones II and V. The mathematical building model (F.E.M Model) of Whole building has been modelled in ETABS 16.2 All the beams and columns are modelled as frame elements. All the slabs are modelled as thin shell elements. To ascertain the seismic load on each floor level of whole structure two types of seismic analysis procedure have been considered as per IS1893-2002 and 2016. Equivalent static approach (linear Static method) and Response spectrum method (Linear Dynamic Method). Parameters considered to understand the seismic response of the multi-storeyed buildings are, Modal Mass participation factor, Modal time period, Lateral displacement, Storey drift, Storey shear of the structure. The whole structural systems are strengthen with vertical shear walls. SAFE (Slab analysis by Finite Element Method) is a software essentially made for analyse and designs of the slabs, since Pile Raft is also a slab therefore SAFE is the ultimate tool for it. Pile Caps have modelled as Slab with Thick plate Action, for base reactions Link between ETABS and SAFE have been used. The parameters consider for finalise the designs of piles and pile caps are, vertical settlement, Punching Shear stress under columns and shear walls and for piles as well. Flexural reinforcements are tabulated in both Longitudinal and transvers direction for the both the faces i.e. Top face and bottom. After all the study a comparison is made between the structure situated in Zone II and Zone V We had observed that when the seismic zones changes and the intensity of seismic forces increases, the design of foundation considerably changes and there is tremendous amount of increase in steel.
