A triangulated cable dome roof having a retractable roof portion includes a triangulated cable arrangement for supporting a roof membrane, a roof membrane which is fixed to a portion of the triangulated cable arrangement so that a portion of the underlying area is exposed, and a retractable roof portion movably secured to the triangulated cable arrangement. The retractable roof portion preferably includes one or more retractable roof sections, each of which is movable between a closed position in which the retractable roof sections overlay the uncovered portion of the triangulated cable arrangement and an opened position in which the retractable roof sections nest above the covered portion of the triangulated cable arrangement, thereby exposing a portion of the underlying area. |

DETAILED DESCRIPTION I have devised a cable dome having a retractable roof portion for an underlying building structure, such as a stadium, arena or the like, which overcomes the disadvantages and shortcomings of the above-mentioned prior art structures.
Specifically, I have devised a lightweight triangulated cable dome having a retractable roof portion.
Advantageously, the triangulated cable dome may be used with non-circular or circular underlying structures.
Moreover, the triangulated structure more efficiently utilizes the tensile property of the building materials thereby creating a lightweight, cost-efficient design.
In accordance with the present invention, a cable dome roof having a retractable roof portion is disclosed.
The cable dome roof includes a triangulated cable arrangement for supporting a roof membrane, a roof membrane which is fixed to a portion of the triangulated cable arrangement so that a portion of the underlying arena is exposed, and a retractable roof portion movably secured to the triangulated cable arrangement so that the retractable roof portion is movable between a closed position in which the retractable roof portion overlays the uncovered portion of the triangulated cable arrangement, and an opened position in which the retractable roof portion nests above the covered portion of the triangulated cable arrangement, thereby exposing a portion of the underlying arena.
Preferably, the retractable roof portion includes one or more retractable roof sections which are movably secured to the cable arrangement to provide a domed structure that may be opened or closed as desired.
In one embodiment, the cable arrangement defines an enclosed area for an underlying building space having a non-circular perimeter including major and minor axes.
The triangulated structure includes a substantially horizontal outer compression ring, first and second fixed end sectors and an intermediate segment that extends from one end sector to the other end sector.
Preferably, a substantially planar cable truss is positioned along the major axis extending from the first end sector to the second end sector
