A tensioned membrane design scheme typically involves the planning and execution of structures made from flexible materials, such as ETFE (Ethylene Tetrafluoroethylene) or PTFE (Polytetrafluoroethylene). These materials are used for their ability to withstand tension, which creates a stable, self-supporting structure. The design process includes considerations for structural integrity, environmental factors, aesthetic appeal, and functionality. This may involve the use of computer-aided design (CAD) software to create detailed plans and simulations to ensure the structural integrity and optimal performance of the membrane.
