description Cable domes have been employed as lightweight, large span roofs. In this paper, several new forms of cable domes are first presented and their geometric feasibility is discussed. A general method, referred to as the DSVD, is next proposed for the determination of the integral prestress modes for various cable domes. Optimum prestressing of domes with a single or with multiple integral prestress modes is also examined. The proposed method is verified through numerical simulations, and is believed to provide a helpful tool in the preliminary design of cable domes.
