Inflatable membrane structure can be divided into air-bearing membrane structure, air-occupying membrane structure (or air-rib membrane structure) and combined gas film (air-bearing air-rib combination).
The air-bearing membrane structure inflates the building indoor through the pressure control system, so as to keep a certain pressure difference between indoor and outdoor, and the membrane body is buoyed and generates a certain pre-tension to ensure the rigidity of the system. The indoor air pressure automatic adjustment system is set to continuously adjust the indoor air pressure to adapt to the change of external load.
Inflatable membrane structure is to inflate a single membrane component to maintain sufficient pressure, and multiple membrane components are combined to form a whole stress system with a certain shape. This structure requires that the membrane material itself has high air tightness, or it needs to be continuously inflated into the membrane structure members.
Tension membrane structure is an important part of modern membrane structure architecture, and the membrane surface is generally negative Gaussian surface. Therefore, it is favored by architects because of its rich form, natural smoothness and soft surface. However, the stress analysis of this structural system is more complicated and requires higher construction accuracy. Therefore, it is difficult to design, calculate and manufacture.
Skeleton membrane structure is a closed and stable skeleton system (generally steel truss system, grid structure, cable net structure or tensegrity system) and membrane material * * * to form a structural stress system. The structure of the system should be similar to the conventional structure (except self-built cable net or tensegrity system), which is easy to be understood and accepted by the engineering community. However, in order to make the membrane have a certain stiffness, the support system provided by the skeleton system should generally have a certain curvature, and a mechanism should be set to prestress the membrane.
As the name implies, a tent with membrane structure is a house with membrane structure.
