Analyses of flexural-torsional buckling of rolling H-section steel mono-overhanging beam
摘要
Abstract
A study on flexural-torsional buckling of rolling H-section Steel mono-overhanging beam under uniform load is carried out. It assumes that when the control section of mono-overhanging Beam under uniform load is on the simply supported part,it can be simplified as a simply supported beam under uniform load and a concentrated couple. This paper has derived the formula of critical moment of simply supported beam under uniform load and a concentrated couple by using energy method,and compared the results by ANSYS finite element analysis, and the proposed formula is accurate enough.关键词
