Membrane structure, also known as tensioned membrane structure, is a new type of building structure developed in the mid-20th century. It generates a certain pre-tensioning stress inside to form a certain spatial shape, as a covering structure, and can withstand a certain external load as a spatial structure form.

Membrane structure is a new type of building structure developed in the middle of the 20th century. Stress to form a certain spatial shape, as a covering structure, and can withstand a certain external load as a form of spatial structure.

Membrane structure is composed of a variety of high-strength film materials (PVC or Teflon) and reinforcing members (steel frame, steel column or steel cable) through a certain way to generate a certain pre-tensioning stress inside to form a certain spatial shape, as a covering structure, It is a form of spatial structure that can withstand certain external loads. Membrane structure can be divided into two categories: inflatable membrane structure and tensioned membrane structure. The inflatable membrane structure is continuously inflated indoors to generate a certain pressure difference between indoor and outdoor (generally between 10mm and 30mm water column). span. The tensioned structure is formed by column and steel frame support or steel cable tensioning. The tensile membrane structure is composed of membrane material, cables and pillars. The soft membrane structure cannot bear the load itself, and can only bear the force after it is taut, so the structure can only bear the tensile force, and it must remain in the tensile state under any circumstances, otherwise it will lose its stability.
