TAKENAKA TECHNICAL RESEARCH REPORT No.70 2014竹中技術研究報告No.70 2014Fig. 11 Lateral load balanceIt was also found that lateral load sharing ratio of piles was estimated about 10 to 20 % of the inertial force of building fromobserved record. It was confirmed that most of the inertial force of the building was transfered to the subsoil through the raft.ACKNOWLEGEMENTSThe authors are grateful to SOHGO HOUSING CO., Ltd. for a great deal of their support to perform the field measurements,especially for the seismic observations.REFERENCES1）Watanabe, T., Fukuyama, H., Horikoshi, K. and Matsumoto, T (2001): Centrifuge modeling of piled raft foundationssubjected to horizontal loads, Proc. 5th Int.
