Abstract:

Large⁃span rigid cantilever truss structures have been widely applied in large venues,convention centers, and airports. Due to short construction periods, complex architectural shapes, andhigh technical difficulty of large⁃scale public buildings in construction, the determination of formworksupport schemes is often crucial for large public buildings. Taking the formwork support system of therigid cantilever truss in Wuxi Olympic Center Stadium as an example, this paper conducts deformationanalysis of the formwork support system and stress calculations for the rigid truss structure to determinethe reinforcement form and shaping effect of the formwork support system.
