网格结构

• The analytic model of the sgscad is based on finite element method and the experimental results that have been provided . to calculate correctly space grid structure , the sgscad utilizes the element of 3d bar or 3d beam that is distinguished by the mode of linking among the members of the structure to simulate varied types of the space grid structure
  利用有限元方法，在已有实验结果的基础上，根据空间网格结构的杆件之间的不同连接方式，采用空间铰接杆系计算模型和空间梁系计算模型来计算不同形式的空间网格结构，编制了基于windows平台的空间网格结构cad软件sgscad 。
