| 摘 要： | 预制预应力混凝土梁柱接合部（PPC-BCC）作为结构构件间柔性连接的主要形式,在建筑、桥梁等结构中具有广阔的应用前景.文中探讨了基于三维杆系结构纤维模型程序实现复杂受力状态下PPC-BCC数值模拟的方法和途径,建立了符合PPC-BCC主要结构特性和受力特点的有限元建模方式.计算结果与试验结果对比表明：由于采用了完善的材料滞回模型和合理的有限元建模方式,本文方法及程序可以较准确用于复杂受力状态下PPC-BCC受力性能的数值模拟.

| Abstract: | Precast Prestressed Concrete Beam-Column Connection （PPC-BCC） is the main form of flexible connections between elements of structures, and has wide prospective applications in building and bridge structures. In this paper, a thorough discussion on how to simulate the hysteresis behaviors of PPC-BCC by a 3D fiber member model program is performed, and a way to appropriately model PPC- BCC with finite element is proposed. The comparison of results between simulations and experiments indicates that, for the reason of using perfect material models and rational model methods, the way and program in this study can be used to accurately predict the bysteretic properties of PPC-BCC under complex loading conditions. |
