Abstract
A clear-span dome for athletic stadia and the like includes a primary network of principal structural members which are interconnected to span a space to be covered and to define the principal curvature of the dome. The network members divide the principal curvature into a plurality of openings of selected configuration. The primary network is supported on foundations, around the perimeter of the space, which carry vertical and lateral loads of the dome. Each opening in the primary network is closed by a secondary dome which has its perimeter connected to the network principal members which form the perimeter of the opening. Each secondary dome has a curvature greater than the principal dome curvature. The primary network can be assembled, without use of shoring, from the perimeter of the space toward the center of the overall dome.
Claims6
A method of erecting a large clear-span dome structure over a space having a perimeter of selected planform configuration, such as the space within an athletic stadium, the method comprising the steps of:
- A. providing horizontal and vertical load supporting means along the perimeter;
- B. spanning the space by interconnecting between the supporting means a principal network of structural members which define a principal dome curvature, and subdividing the principal curvature into a plurality of openings in the network;
- C. closing each said opening with a secondary dome structure having a curvature substantially greater than the principal dome curvature;
- and
- D. connecting each secondary dome structure substantially along the perimeter thereof to the network for transfer of forces developed in the secondary dome due to its own structure and of loads applied to it to the network members and across the network members to adjacent secondary dome structures.
A method of erecting a large clear-span dome structure over a space having a perimeter of selected planform configuration, such as the space within an athletic stadium, the method comprising the steps of:
- (a) providing horizontal and vertical load supporting means along the perimeter;
- (b) spanning the space by interconnecting between the supporting means a principal network of structural members which define a principal dome curvature, and subdividing the principal curvature into a plurality of openings in the network;
- (c) closing each said opening with a secondary dome structure having a curvature substantially greater than the principal dome curvature, including defining each secondary dome structure with its own network of secondary structural members and closures for spaces therebetween, and
- (d) connecting each secondary dome structure to the principal network members for transfer to adjacent secondary dome structures of substantial portions of the forces developed in said each secondary dome structure.
