A significant number of wall-type precast reinforced concrete (WPC) residential buildings exist in Japan that were constructed more than 30 years ago but maintain good structural quality and seismic strength. In order to utilize this building stock, structural renovation is needed such as opening shear walls and addition of elevators, and seismic performance of pre and post renovation is to be evaluated. In authors' previous research, static pushover analysis models were created for standard existing WPC residential buildings under seismic load in the transverse direction. In this research, the models were extended for load in the longitudinal direction. The maximum base shear coefficient, which is defined as the ratio of lateral force to the building weight, is 0.73, and the preliminary failure mechanism is beam yielding, in addition to a limited number of beam shear failures, shear cracking of walls, and bearing failure of the vertical joints. The maximum strength and the failure mechanism calculated using an existing simple seismic performance evaluation method reasonably agreed with that obtained by the models.
