Application of the Conversion Layer of Prestressed Cable-stayed Steel in the Concrete Structural System

ShenZhen Vanke Center Project will widely use the cable-stayed technology of large-span structures such as bridges in construction work,the structure is designed with cable-stayed structure conversion,than a continuous large space will be formed at the bottom of the building.The load of the upper structure will successfully be converted to vertical component through the steel structure of pre-stressed cable-stayed and the ground floor.The particular structural system of its construction process,structural safety and construction process for structural deformation control and so on,is an unprecedented technical problems and challenges.
