摘　　要：对不同宽厚比的冷弯方钢管柱进行有限元分析,考察它们在轴压作用下的反应、应力、应变的分布情况,分析得出其全截面极限强度随宽厚比增大而减小。The cold formed square steel tube columns with different width-thickness ratios are analyzed by FEM. Whose response,the distribution of stress and strain under axial loads are examined. It is concluded that their full sectional ultimate strength is decreased with the increase in width-thickness ratio.

关 键 词：冷弯型钢 宽厚比 性能 轴压
