【摘要】 随着我国经济的快速发展,房价普遍过高,LOFT作为一种时尚的户型,拥有较高且实用的立体空间,所以颇受青年人群的喜爱。这种风格的建筑一般是框架-剪力墙结构的,这使甲方的投资较大,因此框-剪结构LOFT高层住宅的最佳结构方案具有一定研究价值。本文介绍了LOFT的起源和发展、LOFT结构设计的国内外发展现状和前景,以及LOFT高层框-剪结构的基本设计要点、LOFT夹层的结构方案、夹层楼板与主体结构的连接等。将理论作为研究基础,针对LOFT层高大、有夹层的特点,介绍了如何建模及设计时如何对结构计算参数进行选取以及高层建筑结构的设计原则。结合工程实例和概况,根据框架柱占底部倾覆力矩百分比的不同,使用PKPM建立四种不同类型的框-剪结构模型,并使用SATWE子项进行内力分析,得出七个重要的结构参数和经济性指标。使用对比分析的方法对四个方案进行比较,得出框架柱占底部倾覆力矩37.40%的典型框架-剪力墙结构方案的结构合理参数数量最多,经济指标最节俭,是最优方案。对典型框-剪结构进行两个方案的对比,得出剪力墙墙肢截面宽度随建筑高度逐渐变小的方案更优。最后,本文总结了结论并进行分析,在设计相关工程时可对本文的结论进行参考,明确了本文的不足及今后需要深入研究的方向。更多还原

【Abstract】 With the rapid develops generally high,LOFT as a new kind of family,have a higment of our economy,house priceh stereo space,according to the actual measuring a layer of construction area and there will be a layer of more than half of the area[1],among young people,it is quite popular.Its structure form generally adopts the frame-shear wall structure,make the party as investment is larger,so the frame-shear structure LOFT the optimum structure scheme for high-rise residential research has application value.This paper introduces the origin and development of the LOFT,LOFT structure design of the current situation and future development at home and abroad,as well as the basic design of the LOFT high-rise frame-shear structure points,LOFT sandwich structure scheme,mezzanine floor and the main structure of the connection,etc.Will theory as the research foundation,according to the characteristics of the LOFT layer is tall,sandwich,introduced how to modeling and design how to select the structure calculation parameters and the design principle of high-rise building structure.Combined with engineering example and profiles,depending on the percentage of negative moment at the bottom of the frame column,using PKPM to create four different types of frame-shear structure model,and using SATWE subitems for internal force analysis,draw seven important structure parameters and economic indicators.Use the method of comparative analysis of four schemes comparison,it is concluded that37.40% of the overturning moment at the bottom of the typical frame column frame-shear wall structure scheme of the most reasonable structure parameters,economic index is the most economical,is the optimal scheme.For two typical frame-shear structure scheme comparison,it is concluded that shear wall wall limb width of cross section,with the better solution to the smaller building height.Finally,this article summarizes the conclusion and analysis,in the design of related engineering can be reference for the conclusion of this paper,made clear the shortcomings of this article and need further research direction in the future.更多还原
