Abstract
The combined pile-raft foundation is used for high-rise buildings on soft soil since it is an efficient and economical foundation system. The present study deals with evaluation of performance of 15 storey reinforced concrete structures built on piled-raft foundation resting on soft soil under earthquake loads. Finite element analysis of the three dimensional soil-pile-raft-building systems consisting of a combination of long and short piles have been carried out for transient response. The length ratio between the central piles and corner piles is varied from 0.33 to 3 such that the combinations consist of long piles placed at corners or at centre region while short piles are placed at centre or at corners. These systems are subjected to ground motions corresponding to El-Centro and Loma prieta earthquake. The seismic responses of the integrated systems vary with the change in the length of pile.
