To elect pile foundation firmly is one way to satisfy its demands, - making up functions and structure of the building without losing their bearing capacity, or getting differential settlement-. But it use to be uneconomic, so reasonable way is groped for. We have been proposed damage controlled pile foundation using slender support piles and squat earthquake resisting piles. This paper presents the results of experiments using scale model of soil-pile foundation-super structure with the aim of understanding dynamic behaviour of building suppourted by damage controlled pile foundaiton. The results indicate using earthquake resisting piles controlls relative distance between foundation and ground surface, bending moment of support piles.
