The structural design can resist 16 typhoon, and the existing coastal port gas film in Zhongcheng space has successfully resisted 14 typhoon "fireworks". The gas film has the characteristics of flexible structure, and the film material and the net rope itself have high tensile and tear resistance. A gas film laboratory was established in Zhongcheng space. Through the simulation experiment of the core technology of "Numerical Wind Tunnel", it is further verified that its gas membrane structure can successfully resist 16 super typhoon.
