摘要:
提出了波形钢板钢管混凝土柱的有限元分析方法,采用正交异性板来模拟波形钢板。应用ANSYS通用程序对算例进行了分析,并应用有限元方法分析了偏心率、长细比2个主要参数对波形钢板钢管混凝土柱极限承载力的影响。结果表明:可采用稳定折减系数和偏心率折减系数相乘的计算公式来考虑二者对波形钢板钢管混凝土柱极限承载力的影响,其中偏心率折减系数可采用《钢管混凝土结构设计与施工规程》(CECS 28:90)的计算公式; 稳定折减系数应将换算长细比乘以考虑柱肢的钢材型号和混凝土强度等级的材料修正系数,然后采用《钢管混凝土结构设计与施工规程》(JCJ 01—89)的稳定系数计算方法。
Abstract:
A finite element analysis method was proposed for the new type composite column-concrete-filled steel tubular(CFST)column with corrugated steel webs, in which the corrugated steel web was simulated by orthotropic plate. ANSYS program was used to analyze the test specimens. The effects of two critical parameters(eccentric ratio and slenderness ratio)on ultimate load carrying capacityof concrete-filled steel tubular column with corrugated steel webs were analyzed. Results indicate that the formulae, which multiply reductionfactor of stability and reduction factor of eccentric ratio to take influence of eccentric ratio and slenderness ratio into account, can be used to calculate ultimate load carrying capacity. The reduction factor of eccentric ratio can be obtained by the formula inSpecification for Design and Construction of Concrete-filled Steel Tubular Structures(CECS 28:90), and the reduction factor of stability should be got bySpecification for Design and Construction of Concrete-filled Steel Tubular Structures(JCJ 01—89), but the equivalent slenderness ratio should be corrected by multiplying the revised material factor, which takes the grade of steel and concrete into consideration.
