This paper presents the influence of aging and deterioration in wood houses with stucco and bracing. The static loading tests and shaking table tests which were reported in the past study were carried out for old and new walls with stucco and/or bracing. Old one was the wall picked from twenty four years-old wood house. New one was the walls having the same size and specification as picked walls remade using new members to evaluate influence of aging and deterioration. It has been reported that stiffness and strength of old wall was 10-15% lower than them of new one. In this study, time-history analyses are carried out to compare the maximum response between new and old walls during recent observed severe earthquakes. Load-displacement relationships of two wall types were derived from static tests and shaking table test. The capability of time-history analysis model is confirmed comparing with shaking table tests and model results. As the results of analytical studies, it is found that aging and deterioration influence collapse behavior mainly.
