Zhangjiagang's "big butterfly" shines

The Big Butterfly Landscape Membrane Structure Project in front of Zhangjiagang High-speed Railway Station is a single-layer hyperbolic reticulated shell structure system with a symmetrical structure on the plane. The long span of the large wings is about 50m, the short span is about 25m, the small wings are about 35m long, and the short span is about 15m. . The top of the building is a hyperbolic shape, and the highest point of the building is about 17 meters above sea level. The total steel consumption is 800 tons, and the total membrane area is about 7,000 square meters.
