Split Rigidity Method for Analysis of Two-Way Orthogonal-Diagonal Double-Layer Space Grids Structure
In this paper two-way orthogonal-diagonal double-layer space grids structure is assumed as equivalent sandwich plate, and has been analyzed by the non-traditional theory of plate with three generalized displacements, in which shearing deformation is considered. Based upon the split rigidity method, static analysis and natural vibration analysis of two-way orthogonal-diagonal double-layer space grids structure has been studied and the simplified formulas are given out. The comparison with the results of equivalent sandwich plate method shows that as a more simplified method, split rigidity method is as accurate as equivalent sandwich plate method.
