摘要：Latticed shell string structure with inner and outer truss torus, radial cables of which emerge from the roof, is proposed. Ribbed latticed shell string structure with a span of 100m is taken as an example and the modal analysis is performed. The effects of the rises of radial cables and the curvatures of latticed shell on dynamic characteristics of this structure are also investigated. The result reveals some characteristics of modal of the latticed shell string structure with inner and outer truss torus, which could be referenced by structure designers.
