Lad.Shenzhen Guangdong 518040 China; 2.General Contraction Company可f CCTEB Wuhan Hubei430064 China) Abstract:Roof structure of Wuhan Railway Station adopts orthogonal spatial latticed shells structure with multi-tube intersection joints of which the maximum quantity of branch pipe is eight.Some joints have little angle between main pipe and branch pipe or between branch pipes.So there are many overlapping wielding in joint region which influence on joint's strengthen.Plane load experiment of multi-tube intersection joint and finite element analysis prove that multi-tube intersection joint has fine workability and it is safe under special loading mode and has more safety.
