STUDY ON SEISMIC PERFORMANCE EVALUATION OF MODERN WOODEN SCHOOL BUILDINGS IN JAPAN

Japanese school buildings have been changed from modern wooden structures to reinforced concrete structures after the Building Standard Law was established in 1950. Therefore, only a few modern wooden school buildings exist currently. Ensuring the seismic resilience of these wooden school buildings is essentialfor their preservation and longevity. In this study, a static pushover analysis was conductedfor a modern wooden school building using a 3D frame model to simulate the relationship between lateral load and deformation. This 3D frame model was proposed based on the site investigation and the 2D frame model used in a previous study. From the analysis results, it is found that the bearing capacity was decided by the deformation capacity of the column-to-groundsill connection; therefore, reinforcement to these connections was required to improve the seismic performance ofa modern wooden school building.
