The design of park tension membrane involves the planning and construction of tensile membrane structures within public parks. These structures are typically made of lightweight, flexible materials such as ETFE (Ethylene Tetrafluoroethylene) or PTFE (Polytetrafluoroethylene) coated fabrics. The design process includes considerations for structural integrity, aesthetics, environmental factors, and sustainability. It also involves calculating the necessary tension forces, choosing the appropriate membrane material, and ensuring the structural stability of the supporting framework.
