| Outline of Final Research Achievements |
The terrible seismic disaster on steel building structures have been reported. This study proposed the repair technique and estimation method on damaged steel braced structures are proposed.
First, the experimental study is performed on test specimen to reproduce the damaged state of steel braced structures. And the damaged test specimen is restored using proposed repair technique. Furthermore, the experimental loading test is done to clarify the restoring force characteristics related to recovery. From the test results, the proposed repair technique is confirmed, and the relation of repair technique and restoring force characteristics is discussed. And also, to visualize the figure of damaged state, 3D modeling method is adopted. Using the 3D model, the ultimate states of damaged braced structures can be investigated in detail. Furthermore, the limit state analysis method is proposed by consideration of 3D model.
