A tensioned membrane design scheme for water parks typically involves creating a plan for the architectural structure made from a flexible, lightweight material called a membrane. These membranes are stretched over a frame to form a tensile structure. The design must consider factors like structural integrity, weather resistance, and aesthetics. It also involves determining the shape, size, and placement of the membrane, as well as the integration with the surrounding landscape and facilities. This requires expertise in structural engineering, architectural design, and material science.
