Replaceable Brace Modules for Concentrically Braced Frames: Test Results from Substructure with Moment-Resisting Beam-Column Connections

In current practice for concentrically braced frames (CBFs), a gusset plate is typically used to join the brace to the frame elements. Using a linear clearance to accommodate the out-of-plane deformation of the buckling brace can have negative implications for both construction and seismic performance. An alternative connection approach, intended to be more seismically resilient, has recently been developed based on a replaceable brace module …
