Abstract:The complex building is a symbolic building of a spiritual education base. It has the features of complex shape, various functions, and irregular layout. Some columns and the bottom of  roof ceilings require clear concrete effects. The difficulties in structural design were introduced. Based on the results of the overall calculation analysis, the optimization design process of the main structural system was given, and the advantages and disadvantages of the two roof structure solutions were analyzed in detail. Aiming at the structural design of large-span beam and long cantilever beam, the anti-floating problem of mandrel about hollow roof and the design of the formation in building cornice, the corresponding solutions had also been proposed. At the same time, the treatment measures method for overlong structures and expansive soil sites were also given.

Keywords:structural selection; large-span beam; long cantilever beam; hollow floor; overlong structure; slowly bonded prestress
