原始语种摘要: Abstract(#br)The rivet fastened Rectangular Hollow Flange Channel Beam (RHFCB) is a new type of cold-formed steel section, made of two torsionally rigid rectangular hollow flanges, connected to a web via intermittent rivet fastening. The hollow flanges and the absence of free edges in the RHFCB contribute to improved structural performance. The structural behaviour of the RHFCB is unique compared to other conventional cold-formed steel sections and its moment capacity reduces with increasing rivet spacing. The current cold-formed steel design standards do not provide a calculation method to include the effects of intermittent fastening. In this research an extensive parametric study was conducted using validated finite element models to investigate the section moment capacity of RHFCBs....
