Verification of structural health assessment method using full-scale collapse test of four-story steel building

摘要

In this paper, the health status of a full-scale four-story steel building is investigated using the data of collapse test at the E-defense in Hyogo Prefecture, Japan. We extracted the features such as hysteretic characteristics, story drift angle, natural frequency and shapes using only the acceleration data of the collapse test. We evaluated the reliability and the correlation of the features with structural damage. Moreover, we proposed the preferred index for the damage detection.
