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