Abstract The steel roof of Wuhan Gymnasium is a long-span suspendome structure system. According to the structural characteristics of the roof, the lifting installation of upper latticed shell and the installation and tension of lower prestressed cables are introduced in detail. The cable tension is completed successfully on June 27, 2006, while the test results of cable forces and structural deformation are comparatively consistent with the theoretical analysis results. Moreover, Strut-adjustment Method is innovated and applied successfully in the construction of long-span suspendome structure for the first time, and the theoretical and practical experiences can be used for the research and application of similar new-type spatial structures.
