Claims
- 1. 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.
- 2. The method according to claim 1 including performing the spanning step without the use of shoring.
- 3. The method according to claim 1 including providing personnel catwalks in the principal network members, and using the catwalks in performance of the closing step.
- 4. The method according to claim 1 including commencement of the closing step before completion of the spanning step.
- 5. The method according to claim 1 including the defining each secondary dome structure with its own network of secondary structural members and closures there between.
- 6. 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.
