Practice of the design of large span prestressed concrete hollow cast slabTong Weimin(Beijing Building Construction Institute, Beijing 100039，China)

Abstract:The design of cast-in-place prestressed concrete hollow slab is different from concrete hollow cast slab or prestressed concrete slab, these differences should be paid attention to during the design. Some key points and some experiences are described based on the large works of the design and construction of large span cast-in-place prestressed concrete hollow slab in Beijing.
