The present invention relates to a scalable suspension system for domed shaped ceilings that includes a framework of suspension members interconnected to a central hub. The framework of suspension members are used to support a domed shaped ceiling fabricated from plaster or gypsum wallboard. The suspension members include primary spoke members, secondary spoke members, intercostal members and cross tees. The primary spoke members are attached to the central hub component. The intercostal members are spanned between the primary spoke members. The secondary spoke members are connected to the intercostal members, and extend between the primary spoke members. The primary and secondary spoke members are interconnected by the cross tees to create a unified structure. The hub includes radially indexed integral tabs that facilitate the attachment of the hanger wires and allows for the rigid attachment of the primary spoke members in a precise radial pattern.
