Sliding corner gusset connections for improved buckling-restrained braced steel frame seismic performance: Subassemblage tests

•Sliding corner gusset connection is proposed to improve seismic performance of BRBF.•Cyclic tests of three L-shape BRBF steel subassemblages were conducted.•Specimen with the new connection showed superior seismic performance up to 4% drift.•Framing members with the new connection sustained smaller...
