Present Situation and Problems on Aseismic Design of Pile Foundation By H. Hokugo, F. Ohsugi, A. Omika, S. Nomura, Y. Fukuda Concrete Journal, Vol. 29, No. 8, pp. 4-12, Aug. 1986 Synopsis The pile foundation is different from mat foundation in the view point of using the pile material connected with upper construction. So that is directly affected by the behavior of the main building structure and there are many difficult problems on aseismic design about it. This report shows about 4 present pile foundation examples for structural limited design of building under large earthquake, through the practical business by some technical experts.
