WebJan 31, 2024 · In SCBF's, the braces are supposed to buckle first. It's the fuse the pops and breaks the static behavior of the building, allowing the seismic energy to dissipate. By the principle of capacity based design, yes, the anchorage should be designed for that uplift. There is usually an exception to use an overstrength factor though. chris rutt and charles underwood

In general … WebPerformance of SCBF is generally limited by the low ductility exhibited by braces subject to cyclic flexural buckling. This buckling requires the formation of plastic hinges in the brace that undergo significant rotation due to the kinematics of the system. Strains at these plastic hinges can be quite large, leading to fracture under predicted
