Steel structure of butterfly shaped space in front square of Zhangjiagang Station of Shanghai-Nantong Railway

Local Supporting Project of Zhangjiagang Station of Hutong Railway - Butterfly shaped sky Curtain Project at the west side of passenger distribution area in front of the station The proposed structure is a butterfly shaped hyperboloid shell membrane structure in front of the square of Zhangjiagang high-speed Railway Station in Suzhou, which is divided into four parts: large wings and small wings.

The steel structure of this project is a single-layer hyperbolic lattice shell structure system with a symmetrical structure on the plane. The long span of the large wing is about 50m, the short span is about 25m, the long span of the small wing is about 35m, and the short span direction is about 15m. The top surface of the building is hyperbolic shape, the highest elevation of the building is about 17 meters, and the total amount of steel is 1700 tons.
