| description abstract | Beam-columns of a doubly symmetric cross section generally experience overall buckling in a lateral-torsional mode. Members with thin webs and stocky flanges have been shown in a number of studies to buckle in a so-called lateral-distortional mode, involving distortion of the web of the I-section in the plane of its cross section. For simply supported members, it has been shown further that the effects of this web distortion in reducing the overall buckling load is not great. This is not the case for members with elastic restraint, where distortion of the web can be of significance in the buckling behavior. This paper develops a general line-type finite element with 16 degrees of freedom that can be used to study the elastic buckling of restrained I-section beam-columns. The accuracy of the method is demonstrated, and the stability of an elastically restrained half-through girder is studied. | |
