高层框架-剪力墙结构竖向构件几何设计分析

Geometrical design of vertical components of high-rise frame-shear wall structures

对高层建筑的总体结构进行详细且细致的受力和变形分析是比较困难的,往往通过结构分析程序来实现。但在使用计算机程序进行分析时,首先必须要有一个基本确定的结构方案模型,基于模型才能输入平面布置、构件尺寸等相关的原始数据。所以在方案和初步设计阶段,设计人员必须通过概念性近似计算来初步确定该结构的体系和构件的尺寸,并验证设计的可行性。而且概念性近似计算也是不断优化结构总体布置方案的一种简捷有效的途径,不但为计算机整体分析建立了原始数据,也为判断计算机输出结果的正确性提供了可靠的的依据。

Detailed force and deformation analysis of high-rise building structures were difficult,which were usually done by advanced computer programs.Nevertheless,a preliminarily specified model was necessary for the structural analysis by computer programs,from which the basic data such as plane layout and component dimensions were obtained.Consequently,in the process of schematic and preliminary design,conceptual approximate computation was used for determining the dimensions of the whole structure and its components and validating the feasibility of the design.Furthermore,conceptual approximate computation serves as a simple way for optimizing the structural configuration scheme effectively,establishing initial data for structural analysis,verifying the results of the computer program.
