摘　　要：基于前文对空心普通和再生钢管混凝土柱抗震性能的试验和有限元分析,对空心普通和再生钢管混凝土压弯构件的抗震性能进行了理论研究。首先,运用瑞利-利兹法和极限平衡理论等方法对压弯构件在单调荷载作用下的荷载-位移曲线进行了全过程分析。结合有限元参数分析结果,提出了空心普通和再生钢管混凝土压弯构件骨架曲线理论模型和位移延性系数简化计算公式,可为空心钢管混凝土结构工程实践和相关规程的修订提供理论参考。Based on the experimental and finite element analysis of the seismic behavior of hollow ordinary concrete and recycled aggregate CFST columns described in the previous paper, this paper introduces the relative theoretical research on these columns. The overall process analysis of the PA curve of the member under compression and bending has been conducted based on Rayleigh Leeds method and the limit equilibrium theory. Then, the theoretical model on the skeleton curve of the hollow ordinary concrete and recycled aggregate CFST columns and the simplified calculation formula of the displacement ductility coefficient are put forward afterwards. This paper may give theoretical reference to the engineering practice of HCFST structures and the revision of the relative codes.
