Response properties of a reinforced concrete wall-frame system with soft first story were investigated through three-dimensional nonlinear analyses to propose a seismic design method for this system. The analyzed structure was a one-third scaled model of the prototype system designed for this study, which was tested on the Large-scale Earthquake Simulator, National research Institute for Earth science and Disaster prevention (NIED), in July 2000. An outline of the shaking table test and the major findings are also reported. The pushover analysis of the test structure was carried out using the fiber model for columns and the four-node isoparametric element model for shear walls. The overall collapse mechanism was formed with flexural yielding of wall and tensile yielding of columns, however, the mechanism was changed into the story collapse mechanism with the progress of deformation in the soft first story due to the softening of shear wall, which was also observed in the test.
