【摘要】：目前在高层住宅中剪力墙结构所占的比例越来越高，而在剪力墙结构抗震设计中，，连梁的性能对结构有着较大影响，其延性对于剪力墙结构整体的耗能至关重要，在剪力墙结构的设计中，把连梁作为联肢墙弯曲破坏的第一道防线，在普通混凝土连梁设计时，连梁截面受到限制，近年来型钢混凝土结构越来越广泛的在建筑结构中应用，然而作为剪力墙结构的连梁形式出现，能否满足规定，本文正对在普通混凝土连梁和型钢混凝土连梁两种剪力墙结构的抗震性能的分析。本文首先对型钢混凝土结构的发展应用及国内外的研究现状介绍，对连梁在剪力墙结构中的作用、破坏和受力机理进行了说明，然后对所用的中国建筑科学研究院PKPM/SATWE软件和原理进行了介绍，最后对一高层住宅剪力墙结构在普通混凝土连梁和型钢混凝土连梁两种不同模型条件下进行了结构分析，并查看结果是否满足规范，对两种连梁结构模型的重要参数结果对比。通过工程实例的两种连梁形式下的分析，型钢混凝土连梁在结构设计中能够替代普通混凝土连梁，对结构的抗震能力略有提高，其弹性挠度大大减小，由于其含钢率可以较大，所以其在较小截面下更容易满足连梁的抗剪能力问题。为建筑提高更多的空间，对结构更多的功能设计提供更多帮助。
[Abstract]:At present, the proportion of shear wall structure is more and more high in high-rise residential buildings. In the seismic design of shear wall structure, the performance of continuous beams has a great influence on the structure. The ductility is very important to the energy consumption of the shear wall structure. In the design of shear wall structure, the continuous beam is the first line of defense for the bending and failure of the joint wall. In the design of connecting concrete beams, the cross section of continuous beams is limited. In recent years, the type steel concrete structure is more and more widely used in the building structure. However, as the continuous beam form of the shear wall structure, whether it can meet the rules or not, this paper is to analyze the seismic performance of two shear wall structures of concrete continuous beams and type steel concrete beams.
In this paper, the development and application of the steel concrete structure and the present situation at home and abroad are introduced. The effect, failure and force mechanism of continuous beam in shear wall structure are explained. Then, the PKPM/SATWE software and principle of the Chinese Academy of Architectural Sciences are introduced. At last, the structure of a high-rise residential shear wall is mixed in common mixture. The structure analysis is carried out under two different models of the concrete beam and the steel concrete beam. The results are compared with the important parameters of the two continuous beam structure models.
Through the analysis of two continuous beams in the engineering example, the steel reinforced concrete continuous beam can replace the common concrete beam in the structural design. The seismic ability of the structure is improved slightly, its elastic deflection is greatly reduced, because its steel content can be larger, so it is easier to meet the shear ability of the continuous beam under the smaller section. Building up more space will provide more help for more functional design of structures.
