【摘要】：随着科学技术在建筑领域的不断创新与应用，自1886年世界第一栋摩天大楼拔地而起之后，高层建筑在世界范围内迎来了高速发展的时期。伴随着人们对于高层建筑的需求愈来愈多、也愈加的繁杂，高层建筑也就顺势向着更加高的高度，更繁杂的体型、更完美的功能、更加多样化的结构体系发展。这些都导致了结构受力的情况愈加复杂，为结构设计带来了更多的挑战。为了寻求更佳的结构方案，，达到更经济合理的设计，是在超高层结构设计中重要研究课题之一。在超高层结构中设置加强层不仅能减小结构侧移，增加结构整体性，还能达到优化结构布置及构件尺寸的效果，以形成更经济的方案。 本篇文章参阅相关理论文献，对超高层建筑的发展历程，常用的结构体系以及相应的适用范围作了简要的介绍。以重庆市某枢纽中心的一栋塔楼为研究对象，通过SATWE和MIDAS BUILDING建立有限元模型，独立的进行结构设计及相关工作，主要有以下部分： ①.简述了相关高层设计的特点、原则及假定的理论知识，并介绍了加强层的作用机理，对其概念和优缺点进行简单总结。 ②.根据建筑相关资料，初步地完成上部结构的选型及相关的整体弹性计算。 ③.在上述初步方案的基础上，对结构施加加强层，考察加强层对结构的作用。 ④.对设置加强层之后的方案进行结构布置和构件尺寸的优化，并比较分析结果。 ⑤.对优化的方案再次改变加强层的布置，比较结果选择出最适合本结构的加强层方案，并对其进行弹性时程分析和动力弹塑性时程分析，考察其是否满足多遇地震和罕遇地震的需求。 ⑥.针对以上的讨论分析得出结论，对本文的不足与后续的工作进行讨论。
[Abstract]:With the continuous innovation and application of science and technology in the field of architecture, since the world's first skyscraper rose in 1886, high-rise buildings have ushered in a period of rapid development in the world. With more and more people's demand for high-rise buildings, high-rise buildings also tend to higher height, more complex body, more perfect function, more diversified structure system development. All of these lead to the complexity of structural forces, and bring more challenges to structural design. In order to seek better structural scheme and achieve more economical and reasonable design, it is one of the important research topics in the design of super tall structure. Setting the strengthening layer in the super high-rise structure can not only reduce the lateral displacement of the structure and increase the integrity of the structure, but also achieve the effect of optimizing the structure layout and the size of the members, so as to form a more economical scheme. This paper, referring to the relevant theoretical documents, briefly introduces the development course, the commonly used structure system and the corresponding application scope of super high-rise building. Taking a tower building in a hub center in Chongqing as the research object, the finite element model is established by SATWE and MIDAS BUILDING, and the structural design and related work are carried out independently. The main contents are as follows: 1. This paper briefly introduces the characteristics, principles and theoretical knowledge of the related high-level design, and introduces the mechanism of the strengthening layer, and summarizes its concept, advantages and disadvantages. 2. According to the data of building, the selection of superstructure and the whole elastic calculation are preliminarily completed. 3. On the basis of the above preliminary scheme, the strengthening layer is applied to the structure, and the effect of the strengthened layer on the structure is investigated. 4. The structure layout and component size are optimized after the reinforcement layer is set up and the results are compared. 5. For the optimized scheme, the arrangement of the strengthening layer is changed again, and the best scheme of the strengthening layer is selected by comparing the results, and the elastic time history analysis and the dynamic elastoplastic time history analysis are carried out. To investigate whether it meets the needs of frequent and rare earthquakes. 6. In view of the above discussion and analysis of the conclusion, the shortcomings of this paper and the follow-up work are discussed.
