End Plate–Stiff ener Connection for SHS Column and RHS Beam in Steel-Framed Building Modules
Fu Jia Luo,Chenting Ding,Adam Styles,Yu Bai 한국강구조학회 2019 International Journal of Steel Structures Vol.19 No.4
This paper investigates the mechanical performance of beam-to-column connections for steel-framed building modules with RHS and SHS sections of relatively small member sizes. In the experimental program, three forms of connections are tested under static bending, including a completely welded connection (W), a bolted end plate connection (EP) and the proposed end plate–stiff ener connection (ST), and the failure modes, moment–rotation behaviours and strain responses were recorded during experiments. Results show that ST connection exhibited superior connection strength, stiff ness and ductility compared with the EP connection. In addition, a detailed fi nite element analysis was conducted to model the connection behaviours, considering bolt pretension, contact behaviours and detailed bolt geometry, showing good comparison with experiments. Furthermore, a parametric study was performed on the end plate thickness and stiff ener thickness for the proposed end plate–stiff ener connection. Such results fi nally enable a comparative study to investigate the performance of module during road transportation, highlighting the eff ects of connection stiff ness.
