Abstract: A new single-storey warehouse is built for a grain depot in Jiangsu. The warehouse adopts pretensioned and prestressed arch slab roof with a span of 21 m. During construction, a prefabricated platform is built to solve the limited construction field and difficulties in prefabrication and lifting. The lifting steps are reduced to avoid potential quality defects which may appear during lifting. After service and inspection for several years, it is proved that prestressed arch slab roof has many favorable characteristics, such as combination of slab and truss, reasonable force distribution, high strength and rigidity, favorable crack resistance, etc.
