Design of Water Cube's tensioned membrane

Quick answer：

The design of the tensioned membrane for the Beijing National Aquatics Center, also known as the Water Cube, is a pioneering engineering achievement. It features a unique geodesic dome structure made of ETFE (Ethylene Tetrafluoroethylene) foil. This material is lightweight, durable, and has excellent thermal insulation properties. The membrane was tensioned over a steel frame to create a sleek, aerodynamic shape that reflects light and reduces glare. The design not only serves practical purposes but also contributes to the iconic aesthetic of the building.
