摘　　要：冷弯矩形钢管冷成型过程提高了材料的屈服点和抗拉强度同时降低了延性,因而冷弯矩形钢管作为柱材在建筑结构抗震中的应用有待进一步研究。为了验证冷弯矩形钢管整体结构在抗震工程中的有效性,本文对冷弯矩形钢管框架(一榀两层两跨)与焊接箱形框架(一榀两层两跨)进行低周反复荷载作用模拟分析。非线性有限元分析表明,冷弯矩形钢管柱有很好的抗震性能。The cold-formed procedures of cold-formed rectangular steel tube increase the yield point and tensile strength,at the same time,the cold-formed procedures decrease the ductile behavior,so it's necessary to research the aseismic behavior of cold-formed rectangular tube-steel column for architecture structure. In order to demonstrate the validity and accuracy of cold-formed rectangular tube-steel column in integral construction,a two-span two-storey cold-formed rectangular tube-steel column frame and welding box column frame are analyzed.Nonlinear analysis shows that cold-formed rectangular tube-steel column has excellent aseismic behavior.
