In this paper, the effects of various parameters (elastic deformation ratio, strength ratio of left beam to right, stiffness ratio of left beam to right, and base shear coefficient) on seismic damage of joint panels and beams are shown. Seismic responses are analyzed with the fishbone-shaped frame models whose horizontal load carrying capacity and elastic stiffness are constant. The results are as follows. The story drift of frame is not influenced by the above-mentioned parameters so much. But, the damage distribution among members is influenced considerably . Therefore, It is necessary to consider not only strength ratio of members which determines collapse mechanism but also other parameters for the purpose to predict more accurate damage of each member by earthquake.
