摘要

Recently, there are many discussions about repairability and recovery for damagedbuildings after severe disasters, and new keywords such as “Resilience” and“Redundancy” have been closed-up. This paper investigates the repairability ofdamaged steel building structures which experienced severe disasters such asearthquake input motions. At first, the analytical model for repaired steel member isexplained, and also its applicability is represented by comparison with past test results.The next, the ultimate states of steel framed model of original state and repairing stateunder seismic loads are calculated by limit analysis. Herein, an analytical frame modelis designed that the whole story collapse mode is predominated in original state. Andalso, to adjust the failure mode of frame after repair, a various strategy of repairingportion in frame is assumed. From the analytical results, it is observed that the strengthand energy absorption are enhanced if the adequate repairing strategy is adopted togenerate the whole collapse failure mode. That is, it can be said that these repairedframe has high repairability and resilience.
