The concept of membrane structures emerged during the mid-20th century and has since become an innovative architectural solution. These structures are crafted using advanced high-strength film materials such as PVC or Teflon, combined with reinforcing elements like steel frames, columns, or cables. By applying specific pre-tensioning forces, these components work together to create a stable spatial configuration that serves as a durable cover while withstanding various external loads. Membrane architecture can be categorized into two main types: pneumatic membrane structures and tensile membrane systems. Pneumatic membranes maintain their shape through continuous internal inflation, which creates a pressure differential between the interior and exterior spaces—typically ranging from 10mm to 30mm of water column. This pressure difference provides lift to the roof fabric, enabling the structure to span vast distances without additional supports. On the other hand, tensile membrane systems rely on columns, steel frameworks, or cable tensions for stability. Their designs are often praised for their aesthetic appeal and flexibility, offering architects creative freedom to explore dynamic forms. As technology continues to evolve, membrane structures are increasingly being used in diverse applications, from sports arenas and event halls to commercial buildings and public spaces. Their lightweight nature, coupled with their ability to adapt to unique environments, makes them an attractive choice for modern construction projects around the world.
