Development and seismic retrofit of an innovative modular steel structure connection using symmetrical self-centering haunch braces

•An innovative self-centering (SC) modular steel structure (MSS) connection is proposed.•Seismic behaviors of MSS and SC-MSS connections are investigated due to cyclic loadings.•SC-MSS connection exhibits better bearing capacity and self-centering capability.•SC haunch braces can reduce the plastic...
