By the raft's stiffness, it may be expected that the structure with raft foundation has the considerably effect of suppression to differential settlements. In fact, random shaped differential settlements are occurless in case of the structure with raft foundation. And remarkable troubles due to differential settlements can not be seen judging from observations, the addtional stress (a kind of stress caused by differential settlements) may be reduced larger than that of structures with individual footings. Adapting these states, this paper conducts the fundamental analysis and discussion for the stress of raft and structure on the raft foundation when the structure with raft foundation settles differentially, considering the raft foundation is mighty resistive member to differential settlements.
