Abstract: The structural heights of Yuhuan Library and Museum are 15.5m and 24m respectively. Several typical structural units correspond to different functions, forming the overall building group. The roof structure adopts the cupped reinforced concrete suspended cable prestressed thin shell roof, which is a relatively novel prestressed cable-shell composite structure. The floor structure adopts the I-shaped fish-bellied beam box floor, and the vertical lateral force resisting component adopts the shear wall. The structural system and elastic calculation results of the project were briefly introduced. The prestressed tension process of the roof was analyzed, and the key components of the structure were supplemented. The results show that the suspended cable prestressed thin shell roof and I-shaped fish-bellied beam box floor have good performance, and their combination can meet the visual effect and functional requirements of architects. The tension method of suspended cable prestressed thin shell roof used is convenient for construction and reasonable in force. 

Keywords:suspended cable prestress； concrete thin shell roof； cable-shell composite structure； fish-bellied beam；box floor； tension process； key component
