Suspended structure

The terminal of Washington Dulles International Airport is an example of a catenary suspended structure.

A suspended structure is a structure which is supported by cables coming from beams or trusses which sit atop a concrete center column or core. The design allows the walls, roof and cantilevered floors to be supported entirely by cables and a center column.

Another type of suspended structure, suspended catenary, uses outer-wall concrete columns angled away from the center with a cable system strung between them suspending a roof and outer wall structure. In this example there are no supports or visual obstructions inside the structure.
