STUDY OF THE SUSPENDED CABLE-ARCH STEEL ROOF SYSTEM OF ZHENGZHOU INTERNATIONAL CONVENTION AND EXHIBITION CENTER

The steel-roof structure of Zhengzhou International Convention and Exhibition Center uses spatially suspended prestress cable-arch system, which satisfies the needs of internal large space, external long overhanging and uniqueness and lightness in architectural shape.This paper approaches the structural property of the structural layout, construction plan and the damage at each stressing stage.It provides the technical data for increasing the structural security, reliability and economy.It also provides profitable references and engineering accumulations for the design of other similar forms of structure.
