ABSTRACT:
Plates of a tension ring and launch connectors are pressed radially outwardly relative to a circular dome supporting structure by thrust bolts mounted by bearing plates secured to anchor bolts embedded in a bond beam supported by columns to pre-tension the tension ring and load the bond beam in compression. The tension ring plates bear against bolts trapped in connector plates clamped to the bearing plates.
