【摘要】：随着经济发展和建筑工程技术的成熟,各种类型的结构体系迅速发展,结构选型的研究日益被大家所重视。随着房价的日益攀升,人们除注重房屋的质量外,也注重它的经济性能,不管是对于投资者或者是个人都希望房屋能够物美价廉,综合考虑经济因素,使得结构目标效益最大化成为结构选型研究的当务之急。本文以高层建筑结构中比较典型的某二十层的高层单塔建筑结构为选型实例,探讨了高层建筑结构选型的发展趋势及影响因素,提出了高层建筑结构选型中常用的几种结构体系及其优缺点和适用范围,分析了高层建筑结构选型的主要控制指标如水平荷载、轴向变形、侧向位移、结构延性、地震作用、结构延性等。本文选用高层建筑选型中常用结构形式中的纯剪力墙结构、框架—剪力墙结构、框架—核心筒结构这三种结构形式,运用于该选型实例进行建模计算来对比这三种结构形式的周期、内力、位移等指标,对比分析结构整体受力性能,从而找出相对适合二十层左右单塔建筑的合理体系,根据三种结构形式的施工图来采用广联达预算软件,计算出各种结构形式所用的混凝土及钢筋含量指标,分析对比各种结构形式的经济性能选出经济最优方案,结合受力及经济综合分析考虑三种结构体系找出最优方案,使得满足受力前提下结构经济性能最优,为今后此种结构的设计工作提供参考依据。
[Abstract]:With the development of economy and the maturity of construction technology, various types of structural systems are developing rapidly, and the study of structural selection has been paid more and more attention. With the rising housing prices, people pay attention not only to the quality of houses, but also to their economic performance. Whether it is for investors or individuals, they hope that houses will be good and cheap, and that economic factors will be taken into account. It is urgent to maximize the benefit of structural target in the study of structural selection. In this paper, the development trend and influencing factors of high-rise building structure selection are discussed by taking the typical high-rise single-tower structure of a 20-story structure as an example. This paper puts forward several kinds of structural systems commonly used in the selection of tall building structures and their advantages, disadvantages and applicable scope, and analyzes the main control indexes of the selection of tall building structures, such as horizontal load, axial deformation, lateral displacement, structural ductility, seismic action, etc. Structural ductility, etc. In this paper, three kinds of structural forms, such as pure shear wall structure, frame-core tube structure, which are commonly used in high-rise building selection, are selected. Using this model selection example to compare the cycle, internal force, displacement and other indexes of the three structural forms, and compare and analyze the overall mechanical performance of the structure, and find out the reasonable system which is relatively suitable for the 20-story single tower building. According to the construction drawings of three kinds of structural forms, the Wide-Union budget software is used to calculate the concrete and reinforcement content indexes used in various structural forms, and to analyze and compare the economic performance of various structural forms to select the economic optimum scheme. Considering the three structural systems, the optimal scheme can be found by combining the stress analysis and the economic comprehensive analysis, which makes the economic performance of the structure optimal under the condition of the stress, and provides a reference for the design work of this kind of structure in the future.
