本文是钢管混凝土柱模拟一般使用条件下的抗侧力试验研究,对钢管混凝土柱的抗震性能做了初步探讨和理论分析,给出了下限水平屈服荷载的概念及用三折线代替骨架曲线的计算方法;提出了初始延性比的概念和初始延性比、延性比的计算方法;讨论了构件在反复周期的水平荷载作用下各种因素对构件滞回特性的影响,并提出了采用“单位体积耗能率”作为钢管混凝土柱的抗震耗能指标的建议。 This paper is a study on lateral load resistance of concrete-filled steel tube columns under normal conditions of use. A preliminary discussion and theoretical analysis of the seismic behavior of concrete-filled steel tubular columns was carried out. The concept of lower-limit horizontal yield load and the calculation of tri-line replacement of skeleton curves were given. Methods: The concept of initial ductility ratio and the calculation method of initial ductility ratio and ductility ratio were proposed. The influence of various factors on the hysteresis characteristics of the components under repeated cyclic loading was discussed. The unit volume consumption was also proposed. “Rate Rate” as a Recommendation for Seismic Energy Consumption of Concrete-Filled Steel Tubular Columns.
