during this research, the appliance of buckling limited braces (BRBs) for retrofitting abnormal gravity load designed (GLD) RC structures is gifted. a customary six tale residential construction with a soft/weak first tale taken from box survey information in Bangladesh is investigated. The seismic functionality overview of the construction is played utilizing 3D nonlinear dynamic time background research in OpenSees. additionally, this contemporary retrofit process utilizing BRBs is in comparison with conventional retrofit ideas corresponding to concrete jacketing and including masonry infill partitions. The research effects are provided by way of roof float time heritage, greatest ground displacement, greatest tale waft, greatest tale shear, and placement the place damages ensue throughout the research. From the consequences, it may be concluded that BRBs can considerably increase the seismic functionality of the GLD construction. The retrofitted GLD construction utilizing BRBs can face up to as much as serious earthquake with no cave in. in addition, in comparison to standard retrofit concepts, it appears BRBs provide a greater answer when it comes to the seismic functionality, impact to the building's occupancy, and post-earthquake repairing or rehabilitation.
