网架结构的拟板算法研究及参数优化

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。

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

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.
