Split Rigidity Method for Analysis of Double-Layer Space Grids Structure with Rectangular Shape

Abstract:

In this paper double-layer space grids structure with rectangular shape 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 double-layer space grids structure has been studied. The formulas for calculating internal forces, displacement as well as fundamental frequency are given out. The comparison with finite element method and equivalent sandwich plate method shows that split rigidity method is not only simpler than other simplified methods but also of high accuracy.
