Abstract: A full-scale seven-story reinforced concrete building, tested as a part of U. S. -Japan Cooperative Research Program, performed well even under a severe earthquake loading condition. Nonlinear earthquake response analyses were carried out taking into account the base uplifting of a shear wall on the flexible foundation. It was noted that the overall behaviour of the structure, with or without uplifting at the base of the shear wall, was quite similar except for the ductility demand in the foundation girders. The influence of soil flexibility was found remarkable under medium intensity earthquake excitation.
