摘　　要：根据已有弯矩-曲率关系曲线,利用ADINA软件对十形钢管混凝土框架结构进行推覆分析,得到框架结构水平力和位移的关系曲线,同时给出不同混凝土强度、钢材强度、钢管截面面积和肢宽下十形钢管混凝土框架结构水平力-位移的关系曲线,并进行分析和比较。结果表明,十字形截面框架的承载力较矩形截面的承载力有所提高,但延性性能略有降低;钢管截面面积对十字形截面框架的承载力影响显著。According to the bending moment and curvature curves,pushover analysis of reinforced concrete ten shape steel tube frame structures were took out by using ADINA software.The relationship curves of horizontal force and displacement of the frame structures were obtained.The influencing factors of concrete strength,steel strength,section area area of pipe and limb width were analyzed and compared through the force-displacement curves.The results shows that the bearing capacity of the cross section frame is higher than that of the rectangular section,but the ductility performance decreases slightly.The cross sectional area of the steel tube has significant influence on the bearing capacity of the cross section frame.
