Space truss is a spatial structure composed of multiple members connected by nodes in a certain grid form.
The basic units of the grid include triangular cone, triangular prism, cube, truncated pyramid and so on. These basic units can be combined into a plane shape of a triangle, a quadrilateral, a hexagon, a circle or any other shape. It has the advantages of space stress, light weight, large stiffness and good seismic performance; It can be used as the roof of gymnasium, theater, exhibition hall, waiting hall, stadium grandstand canopy, aircraft hangar, two-way large column grid structure and workshop. The disadvantage is that the number of members converging on the node is large, and the fabrication and installation is more complex than the plane structure.
The member section of the grid structure shall be determined according to the strength and stability calculation. In order to reduce the calculated length of compression bar and increase its stability, measures such as adding RE split bar and support bar can be adopted. The joints of plate space truss and double-layer shell space truss made of steel mainly include vane joint, welded hollow ball joint and bolt ball joint. The vane joint is applicable to the grid structure of section steel members. The connection between members and gusset plate is connected by welding or high-strength bolts. Hollow ball joints and bolted ball joints are suitable for space truss structures of steel pipe members. The joints of single-layer shell space truss shall be able to bear bending internal force. Generally, the steel consumption of joints accounts for 15 ~ 20% of the steel consumption of the whole steel space truss structure.
