Abstract

There are many discussions about repairability for damaged building. In previous study, it is reported that strength and rigidity of steel members are improved after repair. However, it is worried that the predominate failure mode of repaired frame is changed. In this study, the repairability of damaged steel subassemblage are investigated experimentally. From the test results, it is confirmed that the predominate failure mode of repaired frame is changed, but it may make the performance deterioration. Furthermore, a finite element analysis is conducted to clarify effectiveness of repair method expansion plan. From these results, it is capable of making the same failure mode as the original.
