| 摘 要： | 通过6个双墙式钢筋混凝土柔性桥墩试验.利用水平位移模拟温度作用,研究了加载速度及配筋率对柔性墩的H-u(水平力与水平位移)曲线的影响,观察了试验桥墩的破坏过程.通过试验及理论分析,提出温度作用下混凝土的σ-ε模式,建立了压弯构件的M-φ(弯矩与曲率)非线性关系.利用数值分析的方法,建立了与试验符合较好的柔性墩H-u理论关系,为类似桥梁工程柔性墩的设计、施工及监控提供了理论参考和计算分析依据.

| Abstract: | Through six double-wall style flexible reinforced concrete piers experiment, the horizontal displacement is used to simulate temperature effect, the influence of loading speed and reinforcement ratio to the H-u(horizontal force and displacement) curve of flexible pier is researched, and the damage process of experimental piers is observed. Through experiment and theoretical analysis, the σ-ε model of concrete under temperature is given, and the non-linear relation of M-φ (moment and curvature) of beam-column is setup. Through using of numerical analysis methods, the H-u relation theory of flexible piers is established which meet the test result better. |
