| Abstract |
Steel structures is consist of steel members as using welding or high strength bolt connection, and plate elements which consist steel member can be treated to 2-dimensional elements. In this study, plate elements are treated to 2-dimensional plane-stress or plane-strain problem. Lee(2007) evaluated maximum internal force of L-type joint element for collapse mechanism based on plastic theory. By expanding that, this study tried to evaluate local collapse loads of column at steel structure connection. Objects of this research is connection with a L-type joint element at upper flange and a rib at lower flange by high strength bolt. It is necessary to possess the internal forces exceeding the external forces subjected each member for steel structures so as to display demanded capacity, and this is a premise for design. Maximum internal forces become an index premise plasticity of composed members. In this study, we are going to evaluate local collapse load of column for column-beam moment connection. Yield line theory apply to evaluation of internal forces. Yield line theory originated in plastic analysis of general plates has an advantage which it presents evaluation formula of internal forces. |
