Grid shape can be divided into a two-tier board structure type grid, single and double-shell type grid structure. Grid plate and double-shell space truss rod into the top chord, bottom chord and web members, mainly withstand tension and pressure; single-shell-type truss rod parts, in addition to withstand tension and pressure from outside the grid arch, but also to withstand the bending moment and shear force. At present, most of China's grid structure using plate grid structure. Research prestressing steel. Prestressing steel use is a high-strength steel instead of part of ordinary steel grid, in order to achieve the purpose of saving steel. From the beginning of the fifties of the prestressing steel theoretical and experimental research qualification grid, until now still not much use in the project, yet to be studied. Spatial structure. Space grid structure to replace the system can save steel flat structure, in large span economic effect is particularly significant, should be further studied.
