【摘要】：高层建筑是反映一个国家，一个城市社会进步和经济繁荣的重要标志。目前我国的高层建筑采用的主要结构是钢筋混凝土结构，它具有强度较高、抗震性能较好，可塑性良好等优点。高层建筑结构体系中，钢筋混凝土框架-剪力墙结构体系既能提供较大的使用空间，又具有良好的抗侧能力，已被广泛用于各类建筑。剪力墙数量和剪力墙布局是否合理，，关系到结构安全性与技术经济合理性。 在实际结构设计中，结构设计人员对剪力墙与框架的设计一般仅仅根据经验，经计算机模拟计算后根据规范进行调整，过程费时且盲目，难以对结构设计形成统一有效的认识。故利用概念设计原理对框架-剪力墙结构的安全与可靠性进行研究，多次计算分析，以提高建筑物的安全性和合理性。 本文在阅读和参考国内外近些年的文献的基础上，对框架-剪力墙结构的剪力墙优化理论和分析方法有一定的了解后，基于框剪-剪力墙结构中合理的剪力墙位置和数量对结构刚度、水平侧移等有影响。主要进行了如下工作： （1）以建筑方案为依据，在满足结构设计和规范要求的基础上，选择四种不同的剪力墙布置模型，分别采用有限元分析软件SAP2000和PMCAD SATWE进行了建模和分析。 （2）分别采用SAP2000和SATWE的振型分解反应谱法分析计算框架-剪力墙结构的内力和位移，依据规范，通过对比各种结构模型的剪重比、刚重比、周期比、弹性层间位移等参数，判断各模型剪力墙布置的合理性，选择最合适的剪力墙布置模型；同时对框架与剪力墙如果更好的协同受力进行初步探讨，并分别得出两种有限元分析软件对剪力墙合理性分析的结果。 （3）对比SAP2000和SATWE的分析结果，说明两种软件在分析过程中参数选取的联系性，结合联众软件的分析结果得出剪力墙的合理数量和布置的相关结论，并且为框架-剪力墙结构在实际工程中的运用提供一些合理性的建议。
[Abstract]:High-rise buildings are an important symbol of a country, a city's social progress and economic prosperity. At present, the main structure used in high-rise buildings in our country is reinforced concrete structure, which has the advantages of high strength, good seismic performance, good plasticity and so on. In high-rise building structure system, reinforced concrete frame-shear wall structure system can not only provide a large space for use, but also have a good ability to resist side, so it has been widely used in all kinds of buildings. Whether the quantity of shear walls and the layout of shear walls are reasonable is related to structural safety and technical and economic reasonableness. In the actual structure design, the design of shear wall and frame is only based on experience, which is adjusted according to the code by computer simulation calculation. The process is time-consuming and blind, so it is difficult to form a unified and effective understanding of structural design. Therefore, the safety and reliability of frame-shear wall structure are studied by using the principle of conceptual design, and the safety and rationality of the building are improved by calculating and analyzing many times. On the basis of reading and referring to the literature of recent years at home and abroad, this paper has a certain understanding of the theory and analysis method of shear wall optimization of frame-shear wall structure. Based on the reasonable position and quantity of shear wall in frame-shear wall structure, the stiffness and horizontal lateral displacement are affected. The main works are as follows: (1) based on the construction scheme, four different shear wall layout models are selected on the basis of meeting the requirements of structural design and specifications. The finite element analysis software SAP2000 and PMCAD SATWE are used to model and analyze. (2) the internal force and displacement of frame-shear wall structure are calculated by SAP2000 and SATWE mode decomposition response spectrum method, according to the code. By comparing the shear weight ratio, rigid-weight ratio, period ratio, elastic floor displacement and other parameters of various structural models, the rationality of the shear wall layout of each model is judged, and the most appropriate shear wall layout model is selected. At the same time, if the frame and shear wall have better synergistic force, the results of two kinds of finite element analysis software for the rationality analysis of shear wall are obtained. (3) comparing the analysis results of SAP2000 and SATWE, This paper explains the connection of parameter selection in the analysis process of the two kinds of software, and draws the conclusion that the reasonable quantity and arrangement of shear wall can be obtained by combining the result of the software analysis. Some reasonable suggestions are provided for the application of frame-shear wall structure in practical engineering.
