原始语种摘要: Abstract(#br)This paper presents the results of an experimental study on the section moment capacity of cold-formed steel beams with rectangular hollow flanges. The new Rectangular Hollow Flange Beam (RHFB) is fabricated using a unique manufacturing process in which two cold-formed rectangular hollow flanges are screw fastened to a web plate. It possesses unique stress-strain characteristics and initial imperfections that are different from conventional open cold-formed steel sections and welded hollow flange beam sections. In this study, the section moment capacity of RHFBs was investigated using a series of full scale bending tests. Twenty two section moment capacity tests of RHFBs were conducted on short span flexural members with simply supported end conditions for three steel grades...
