Central Plaza Project

The structure adopts the lattice shell space structure system, and the cross section of the truss members should be determined according to the strength and stability. In order to reduce the calculating length of the pressure rod and increase its stability, additional auxiliary rod and support rod can be adopted. The joint forms of steel plate mesh and double shell mesh mainly include cross plate joints, welded hollow ball joints and bolted ball joints. The cross plate joints are suitable for steel grid structure. The connection between the tie rod and the node plate is welded or high-strength bolted.
