Since Hanshin - Awaji (Kobe) Earthquake, a lot of those high ground level accelerations were observed in various regions in Japan when Niigata Chuetsu Earthquake, Niigata Chuetsu Coast Earthquake and Fukuoka West Coast Earthquake occurred. A present structure has the possibility of experiencing several earthquakes. And the structure is greatly damaged for resonance cyclic response after that the strength decrease of structure is caused. Therefore, cyclic loading tests of plywood bearing shear walls were conducted by authors. And through those cyclic loading tests, the strength decrease was occurred with cyclic deformation. And the change of strength decrease were approximated. In this report, the analtical hysteric model with strength reduction is proposed. And the influence of the strength reduction was examined by analysis in one earthquake. As a result of analytical examinations that used 17 kinds of earthquakes, the response deformation has been increased around 20% more than the deformation of non considered model.
