Abstract
Biaxial bending and compression is general stress state of the main material and signal diagonal member of angle steel tower,in view of complexity of theoretical analysis on ultimate bearing capacity of the biaxial compression-flexure member of single-angle steel,this paper uses finite element software ANSYS and considers initial bending and remnant stress of the member to carry out numerical analysis on the biaxial compression-flexure member and discusses influence of slender-ness ratio,eccentricity,section dimension,member force distribution and initial imperfection on ultimate bearing capacity of the compression-flexure member. Results indicate that the larger eccentricity is,the lower bearing capacity is,and nega-tive influence of eccentricity gradually decreases with increase of slenderness ratio of member. In addition,bearing capacity of bending member with reverse curvature is greater than that of bending member with single curvature. It compares result of finite element analysis with formulas in AISC 360-10 and suggests to adopt the later in design which is more safer.关键词
