ƒ^ƒCƒgƒ‹i‰pjF ANALYSIS ON REGIONAL CHARACTERISTICS OF SEISMIC PERFORMANCE INDICES OF WOOD-FRAME BUILDINGS IN JAPAN BASED ON THE RESULTS OF SEISMIC CAPACITY EVALUATION
´˜^i‰pjF The regionality of seismic performance indices is analyzed based on the results of seismic capacity evaluation employed to buildings of all over Japan. The evaluation results are aggregated into eight regions: Tohoku, Kanto, Hokushinetsu, Chubu, Kansai, Sanyo, Shikoku, and Kyushu, considering culture and climate. The distributions of the construction year and total area of floor space are examined of their similarity to those of Housing and Land Survey taken by the Statistics Bureau of Japan. Buildings in Tohoku show the lowest performance indices in eccentricity, but the highest in horizontal resistance. The ratio of buildings with construction year older than 1981 and area less than 50 m2 should be adjusted to that of the survey result because they have poor performance indices.
