【摘要】：随着国民经济及现代建筑技术的发展,人们开始对周围生活环境的品质有了更高的要求。为了满足建筑艺术及人们对美好生活环境的追求,越来越多的大空间、大跨度的建筑结构被建造出来。拉索点支式玻璃幕墙作为现代建筑科技和艺术的完美结合的外围护结构,其外形构造上能够提供更大的空间跨度和视野,深受现代建筑艺术人士的喜爱,具有广阔的市场前景。虽然玻璃幕墙结构在我国有了较大的发展,但是对于玻璃幕墙在结构设计过程中还没有形成一套比较完整、成熟的设计理论。本文从玻璃幕墙结构组成进行介绍分析,以某一工程实例为背景,结合有限元分析原理,建立有限元分析模型对拉索点支式玻璃幕墙结构进行了分析,主要工作如下：1)对玻璃面板的破坏原因进行了介绍,建立玻璃面板的ansys有限元模型,对影响玻璃面板承载性能的因素进行分析,并应用MATLAB软件对玻璃面板的挠度和应力进行数值计算。分析玻璃面板的厚度,边界条件、玻璃的几何形状及开孔大小等因素对玻璃面板承载力的影响。2)以某一工程实例为背景,研究双层拉索点支式玻璃幕墙结构随玻璃面板厚度、拉索的预应力和撑杆高度的变化对玻璃幕墙结构的挠度的影响情况。3)利用线性滤波法中的扩展回归AR模型,通过MATLAB工具编程求解玻璃幕墙结构所受脉动风速度。4)通过MATLAB工具对幕墙结构所受到的脉动风进行模拟,模拟得到玻璃幕墙结构受到的脉动风压时程变化数据。求解玻璃幕墙整体结构在脉动风荷载作用下的结构位移响应,并与静力法求解结果作对比。5)利用Ansys中的时程分析方法,采用EI和Tafat地震谱对模型进行地震响应求解。分析不同的地震波谱作用下的幕墙结构的响应。本文的结论能用于双层拉索点支式玻璃幕墙结构,能够为同类幕墙结构的设计提供参考,具有很好的工程价值使用价值。
[Abstract]:With the development of national economy and modern building technology, people begin to have higher demands on the quality of living environment. In order to satisfy the architectural art and people's pursuit of better living environment, more and more large space and long span architectural structures have been built. As a perfect combination of modern architectural technology and art, the glass curtain wall with lasso point support can provide a larger space span and visual field, and is loved by modern architectural artists and has a broad market prospect. Although the glass curtain wall structure has made great progress in our country, but the glass curtain wall in the structure design process has not formed a set of relatively complete, mature design theory. In this paper, the composition of glass curtain wall structure is introduced and analyzed. Based on a project example, a finite element analysis model is established to analyze the glass curtain wall structure with cable point support. The main work is as follows: (1) the causes of failure of glass panel are introduced. The ansys finite element model of glass panel is established, and the factors influencing the bearing capacity of glass panel are analyzed. The deflection and stress of glass panel are calculated by MATLAB software. The influence of the thickness of glass panel, the boundary condition, the geometric shape of glass and the size of opening hole on the bearing capacity of glass panel is analyzed. Based on an engineering example, the double layer cable supported glass curtain wall structure with the thickness of glass panel is studied. The influence of the prestress of cable and the height of braces on the deflection of glass curtain wall structure. 3) the extended regression AR model is used in the linear filtering method. The pulsating wind velocity of glass curtain wall structure is solved by MATLAB. 4) the fluctuating wind velocity of glass curtain wall structure is simulated by MATLAB tool, and the time history data of fluctuating wind pressure on glass curtain wall structure are obtained by simulation. The displacement response of the whole glass curtain wall structure under pulsating wind load is solved and compared with the static method. 5) using the time-history analysis method in Ansys, the seismic response of the model is solved by ei and Tafat seismic spectra. The response of curtain wall structure under different seismic spectrum is analyzed. The conclusion of this paper can be used in the double-layer cable point-supported glass curtain wall structure, can provide reference for the design of the similar curtain wall structure, and has good engineering value.
