EVALUATION OF MAXIMUM DRIFT ANGLE AND TOTAL COLLAPSE RATE OF WOODEN HOUSES FOR THE 2024 NOTO PENINSULA EARTHQUAKE

Abstract

 In this study, we evaluated the maximum drift angle of wooden house models using the performance equivalent acceleration response spectrum at earthquake observation sites where the major damage ratio of wooden houses was investigated in the 2024 Noto Peninsula earthquake. In addition, the major damage ratio of wooden houses was calculated based on the distribution of strength by building age and the maximum drift angles. As a result of the analysis, the major damage ratio of wooden buildings was high at earthquake observation points where seismic motion with a period of 1 to 2 seconds was large. Finally, the major damage ratio of wooden houses of all ages was compared with the results of the damage survey.
