Abstract：To enhance theconstruction eficiencyand structural stability of prefabricated steel structures，this study proposes a novel back-to-back double-corrugated-plate connection for primary and secondary beams.The connection system comprises double-corrugated steel plates and two cold-formed channel steels.Static load tests were conducted on 22 groups ofspecimens to analyze their failure modes and load-displacement curves，thereby elucidating the underlying mechanical behavior and load-transfer mechanisms.The results demonstrate that the installation of cold-formed channel stelswithin the corrugated webs effectively constrains out-of-plane deformation，thereby improving the load-bearingcapacityand overallstabilityof the connection.The failure modes observed were either bolt shear-through or fracture at the bends of the corrugated plates.The normalized ultimate shearcapacitywas foundtobeprimarily governedbythe thickness，height，and lengthof thecorrugated plates，while it remained independent of the widthsofthe flatand inclined plate segments.A predictive formula for estimating the normalized ultimate shear capacity isderived.The findings of this study offer valuable insights for the application of such connections in steel structures.
