【摘要】：剪力墙结构是一种主要的高层建筑结构体系,其横向刚度大,承受竖向力尤其是水平力的能力强,可以建造高度更高、层数更多的建筑,特别适合于建造开间进深比较小的建筑,比如住宅、宾馆、单身宿舍等,在现代高层建筑,特别是民用住宅类建筑中的应用十分广泛。有鉴于此,对高层建筑剪力墙结构进行力学性能和优化设计方面的研究有一定的实践意义。文中第二章结合实际工程,介绍高层剪力墙结构的设计和分析方法,从建筑识图开始,介绍截面估算、荷载计算、结构布置、软件计算、结果查看及调整。在多遇地震弹性结构分析中通过SATWE软件计算模型的周期比、刚重比、剪重比、层间位移角、侧向刚度比、受剪承载力比、位移比等七项指标,并通过YJK软件计算对所得指标进行对比,对所建立的剪力墙模型的合理性进行判断与分析。同时还对本结构设计中涉及到的结构概念进行介绍。本文第三章选取影响结构整体性指标和经济性指标三个因素,即剪力墙厚度、混凝土等级、洞口率,建立27个对比模型,定量分析其对整体性指标和经济性指标的影响,并总结出针对中低烈度区的高层剪力墙结构的优化思路和原则。本文第四章结合第三章中所提出的优化思路和原则,针对原设计方案提出优化设计方案,给出优化原因,通过计算分析,比较优化后与优化前的整体性指标和经济性指标,以说明结构方案的合理性。
[Abstract]:The shear wall structure is a kind of main tall building structure system, its lateral stiffness is large, the ability of bearing vertical force, especially horizontal force is strong, can build the building with higher height and more storeys. It is especially suitable for the construction of small buildings, such as residential buildings, hotels, single dormitories, etc., which are widely used in modern high-rise buildings, especially in civil residential buildings. In view of this, it has certain practical significance to study the mechanical performance and optimization design of shear wall structure of high-rise building. In the second chapter, the design and analysis method of high-rise shear wall structure is introduced, starting with building drawing, section estimation, load calculation, structure layout, software calculation, result view and adjustment. The periodic ratio, rigid-weight ratio, shear-weight ratio, interstory displacement angle, lateral stiffness ratio, shear bearing capacity ratio and displacement ratio of the model are calculated by SATWE software in the analysis of elastic structures with frequent earthquakes. The rationality of the established shear wall model is judged and analyzed through the comparison of the obtained indexes through the calculation of YJK software. At the same time, the concept of structure involved in the structure design is also introduced. In the third chapter, we select three factors which affect the integrity index and economic index of structure, that is, the thickness of shear wall, the grade of concrete, the ratio of hole, and set up 27 comparative models to quantitatively analyze its influence on the integrity index and economic index. The optimization idea and principle of high-rise shear wall structure in low-and low-intensity area are summarized. In the fourth chapter, combined with the optimization ideas and principles proposed in the third chapter, the author puts forward the optimization design scheme for the original design scheme, and gives the optimization reasons. Through calculation and analysis, the integrity index and economic index after optimization and before optimization are compared. To illustrate the rationality of the structural scheme.
