摘要
对单轴对称截面铝合金挤压型材压弯构件的平面内稳定承载力进行了数值分析,通过参数分析推算了其受拉屈服验算公式中的修正系数η2,建议η2对弱硬化合金取1.15、对强硬化合金取1.25,这样可使相关公式的计算结果较为合理地满足设计要求。
Numerical analysis was executed to study the in-plane stability capacity of extruded aluminium alloy beamcolumns of single symmetric sections, and a modified coefficient η2 in the interaction expression was calculated by parameter analysis. Based on above analysis, η2 was proposed to be 1.15 for weak hardening alloy and 1.25 for strong hardening alloy, which have been verified by comparison with numerical calculation results.
