网架结构的拟板算法研究及参数优化

Study on equivalent stiffness plate method on grid structure and optimeze of parameter

指出网架结构是一种高次超静定的空间杆系结构,完全精确地分析它的内力和变形是相当复杂和困难的,在初步设计时亦是没有必要的,拟板法可以作为参考数据或快速估算的方法,本文成功建立了网架拟板模型,并对模型进行了算例验证计算。

It points out grid structure is fairly complicated and difficult to precisely study the internal force and deformation of grid structure because it＇s a high order hyperstatic space member structure. Sometimes it is not necessary. Equivalent stiffness plate method could be adopted as a method of reference data and instant calculation. In the thesis stiffness equivalent plate are successfully built and examples validation calculation are also eonducted.
