SUSPENSION AND MEMBRANE:

Suspension and membrane is a structural system largely based on tension. Compression members are only used as a means of erecting and suspending the tensile objects. Because the system is tensile-based, the structure can span across larger distances, making it advantageous for large spaces that need central openings.

Suspension and membrane structures are typically easy to identify, as the form very closely follows the force. As identified by the arrows on the diagrams, the load paths directly follow the curves in the membrane and the pull of the cables. From these two tensile structures, the forces are then distributed into the compression members, which are most typically columns.

Advantages for suspension and membrane structures are their ability to create large spans or accommodate for large roof openings. This kind of structure typically works best in the form of stadiums or arenas. Due to changing loading conditions, there is a disadvantage for structural stability if tensile cables fall into compression.
