Verification of Damage Evaluation Method based on Measurement of Relative Story Displacements through E-Defense Test

摘要

This study presents the experimental verification of a damage monitoring and evaluation method for building structures based on the measurement of Relative Story Displacements (RSDs). The damage evaluation method is formulated to detect the damaged locations of structural elements and evaluate their damage degree based on the displacement loading analysis by the time histories of measured RSDs. Furthermore in the evaluation process, the analytical technique is introduced to compensate for the measurement errors associated with the properties of sensors. The monitoring accuracies are analyzed through the shaking table test of a full-scale 4-story steel-moment resisting framing building carried out at E-Defense in Japan. The results indicate the effectiveness of the proposed damage evaluation method in its applications to the Structural Health Monitoring (SHM) system.
