【摘要】：目的研究装配式混凝土框架-剪力墙结构的整体受力性能,为其工程设计提供数据参考.方法以一榀三层三跨混凝土框架-剪力墙为计算模型,采用通用有限元软件ABAQUS分别对装配式结构和现浇结构进行低周往复加载计算.结果装配式结构的承载力要低于现浇结构,刚度退化过程中装配式结构的侧向刚度小于现浇结构,装配式结构加载后期耗能要小于现浇结构,但装配式结构的延性要优于现浇结构.结论装配式结构的破坏模式与现浇结构有一定区别,设计时应在薄弱部位采取相应的构造措施予以保证.
[Abstract]:The purpose of this paper is to study the overall mechanical behavior of the prefabricated concrete frame-shear wall structure, and to provide a data reference for its engineering design. Methods A three-story three-span concrete frame-shear wall is used as a calculation model. The general finite element software ABAQUS is used to calculate the low cycle reciprocating loading of the assembly structure and the cast-in-place structure respectively. The results show that the bearing capacity of the assembled structure is lower than that of the cast-in-place structure, and the lateral stiffness of the assembled structure is smaller than that of the cast-in-place structure during the process of stiffness degradation. The energy consumption of assembly structure is smaller than that of cast-in-place structure at the later stage of loading, but the ductility of assembly structure is better than that of cast-in-place structure. Conclusion the failure mode of assembly structure is different from that of cast-in-place structure. In the design, the corresponding structural measures should be taken in the weak part to ensure.
