FACTORS AFFECTING ULTIMATE LOAD-CARRYING CAPACITY IN- PLANE OF TAPERED MEMBER
Thin and high webs are adopted in tapered H-section members. These design methods fully develop flange-bearing capacity, and can lead to local buckling of web,but this does not mean losing bearing capacity. Based on the non-linear shell element method, analysis for ultimate load-carrying capacity of tapered H-section column in plane has been performed. Considering the interaction of web local buckling and overall buckling of member, the effects of web width to thickness ratio, flange width to thickness ratio, slenderness ratio of member and web tapering ratio on ultimate load-carrying capacity of column are analyzed and evaluated systematically. By comparing the results obtained from the method with those of Chinese current Technical specification for steel structure of light-weight buildings with gabled frames,some valuable conclusions are drawn.
