The method of welded steel support plates to adjacent rods is proposed to reinforce the tensile ball nodes of grid structures.The method comprehensively considers the material,space structure and scale effect of bolted spherical nodes and members,Because the support plates are welded to adjacent rods of bolted spherical nodes,this method is easy to operate and can be widely applied to reinforcement projects of various tensile spherical nodes.Through simulation and experimental verification,the bearing capacity of the node domain after welding support plates is greatly improved,which can achieve a good reinforcement effect.This method provides a new idea for the reinforcement of tensile spherical joints.
