Image-GoddenE24 New United Nations Building. View of the dome underneath and looking upwards. The dome is primarily one of radial arch-type ribs, though the small circumferential members will provide some hoop tension. (Geneva, Switzerland) | |

Image-GoddenE25 Church building. Built in 1968 this small semicircle building is topped with a simple dome consisting of radial reinforced concrete ribs connected to ring beams top and bottom, and capped with a lantern. (Chicago, Illinois) | |

Image-GoddenE27 Assembly Hall, University of Illinois, Urbana. 400 ft diameter ribbed reinforced concrete dome. The ribs are folded-plate construction. Dome was cast on falsework, then the ring-beam on which it rests was prestressed by wrapping with steel wire under high tension until the dome became self-supporting. (Urbana, Illinois) | |
|
Image-GoddenE28 Assembly Hall, University of Illinois, Urbana. Close up of the dome showing the radial cantilevers from the ground which support the dome ring-beam. (Urbana, Illinois) | |
|
Image-GoddenE29 Assembly Hall, University of Illinois, Urbana. Inside view of the dome showing the arena seating and the form of the folded-plate construction used to provide the dome with the necessary moment-carrying capacity in the radial direction. (Urbana, Illinois) |
