Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Can be used to simplify the calculation, such as the cross-beam system differential analysis, the proposed plate method internal force and displacement calculations. Monolayer shell grid nodes are generally assumed to be rigid Stadium grid, should be rigid rod finite element method calculation; double-shell type truss rod can be articulated finite element method calculation. Single and double shell grid can also simplified method of simulated shell calculations. After continuous development of new spatial structure of a century grid cost, in terms of structure, in addition to the grid, mesh shell, membrane structures, tensegrity system, opening and closing the roof, collapsible structures are spatial structures members.
