| 摘 要： | 对不同长细比的冷弯方钢管柱及四面焊接方钢管柱进行有限元分析,考察其在轴压和水平力作用下的反应、应力、应变的分布情况,得到相应的滞回曲线,分析冷弯钢管和四面焊接钢管柱延性、滞回特性、耗能、破坏特征等,研究表明冷弯型钢柱的抗震性能与四面焊接管的抗震性能比较接近。

| Abstract: | Different slenderness ratio of cold-formed square steel columns under cyclic horizontal loading are researched by FEM analysis.the stress and strain distribution and hysteresis loop are obtained and compared with those of box section columns.The ductility and hysteretic behavior and energy dissipation behavior and failure characteristics are analyzed also.The results show indicate seismic behavior of cold-formed square hollow section columns is close to that of box section columns. |
