摘　　要：在考虑混凝土本构关系下降段及纵筋粘结滑移的基础下，根据钢筋混凝土双向压弯柱的工作原理。提出了一种钢筋混凝土异形柱的非线性分析方法。并编制了相应的计算机程序。着重分析了在不同轴压比和荷载角作用下纵筋粘结滑移对截面N-M-φ关系全曲线的影响。得出的结果与试验结果吻合较好。Based on the consideration of decline section of stress-strain relation of concrete and the sliding of longitudinal reinforcement anchoring, according to the operational principle of the column subjected to biaxial eccentric loading, put forward a nonlinear analysis method for special-shaped reinforced concrete column, and weaved a corresponding computer program. Analyzed the effect that the sliding of reinforcement anchoring on N-M-φ curve under different axis-press ration and load angle, The results are very close to the test.
