This paper describes the development of a simplified nonlinear analysis to predict behavior of a horizontally loaded piled raft foundation. In the proposed method, two new effects have been introduced to the previous method. One is the change of ultimate soil resistance against piles due to the contact between the raft and the underlying soil. The other is the rotation of the raft due to the bending moment from piles and also to the change of the contact pressure distribution caused by the pile movement. A comparison with centrifuge test of piled raft foundations and freestanding pile groups indicates that the proposed method can give a fairly good prediction of the behavior of a horizontally loaded piled raft foundation.
