The State-of-the-art review on development of replaceable fuse components in resilient moment resisting frame

Abstract

The current study is consistent with the ongoing research on constructing resilient structures by restricting damage inside replaceable components at expected locations employed in moment-resisting frames (MRF) and related typology. Innovative, resilient steel connections with isolated or integrated designs of replaceable components adjacent to the column face, in the center of the beam, and at the base of the column have been investigated in the most recent literature. A total of 196 papers during the past 23 years, i.e., from 2000 to 2022, are critically reviewed. The detailed review reveals that the work has focused on the development of steel structure typologies with small replaceable components or fuse elements which may have the capability to dissipate seismic energy. These low damage fuse components keep the structure elastic state during design basis earthquakes and allow for cost-effective post-earthquake restoration following a major seismic event. Further, statistical analyses of the literature are performed using trend, percentage contribution, and term co-occurrence maps. Lastly, research gaps are recognized, and future scope in the domain is suggested.
