Analysis on the mechanical behavior of the grid by using the equivalent stiffness method

The author introduces the general idea of analyzing the grid by using the equivalent stiffness method,analyzes the mechanical behavior by using the equivalent stiffness method in the elastic stage of the grid,carries out the finite element analysis of the grid model based on the elastic plate analogy method,and carries out the comparative analysis of the calculation results of the plate analogy model,to evaluate the accuracy of the plate analogy method.
