Research on Section Classification of Cold-formed Thin-walled Steel Pure Bending Members
In order to study the section classification of cold-formed thin-walled lipped channel steel pure bending members,a large number of parameter analyses of cold-formed thin-walled lipped channel steel pure bending members with different width-to-thickness ratios of plates were carried out by using the verified finite element model.The results show that the flexural capacity is inversely pro-portional to the width-to-thickness ratio of flange and web.On the premise of considering the correlation between flange and web,the width-to-thickness ratio limit of plate section was obtained based on the bearing capacity of section,and the section classification meth-od of cold-formed thin-walled lipped channel steel pure bending members is proposed.
