双波板主次梁连接节点的抗剪性能试验研究
Experimental study on shear performance of double-corrugated-plate primary-secondary beam connections
摘要
Abstract
To enhance the construction efficiency and 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 of specimens 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 steels within the corrugated webs effectively constrains out-of-plane deformation,thereby improving the load-bearing capacity and overall stability of the connection.The failure modes observed were either bolt shear-through or fracture at the bends of the corrugated plates.The normalized ultimate shear capacity was found to be primarily governed by the thickness,height,and length of the corrugated plates,while it remained independent of the widths of the flat and inclined plate segments.A predictive formula for estimating the normalized ultimate shear capacity is derived.The findings of this study offer valuable insights for the application of such connections in steel structures.关键词
