| 摘 要： | 在实际地震作用下，高层，特别是高宽比较大的高层结构中，由于倾覆力矩的作用、柱子、特别是外边柱所受轴力的变化将不可忽略。轴向变形与双轴弯曲的耦合作用，将是柱子塑性变形的显著特征。基于材料本构关系的“纤维模型”，能较精确地反映轴向变形，双轴弯曲三者之间的耦合作用。一组钢筋混凝土柱子双轴压弯的计算结果与试验结果的比较，证明了“纤维模型”的有效性和精确性。

| Abstract: | The changing of axial forces in columns of high rise buildings under earthquake is not negligible. Plastic deformations in different degrees of freedom happening in the same cross section of a column are coupled. Fiber Model works well in calculating the coupled deformations in reinforced concrete columns, which is verified by the comparison between test and calculation results of 7 specimens of RC column under 7 different biaxial loading paths in this paper. |
