Abstract:Zhaoqing New District Sports Center is composed of a professional football stadium, a gymnasium (including  a main gymnasium,  a training hall and city living room connecting the main gymnasium and the training hall). Every individual building adopts the reinforced concrete frame structure. The roof system of the professional football stadium is the cantilever steel box girder structure, and the roof systems of the gymnasium and the training hall adopt the suspendome structures. The determination of the structural system, large-span steel roof system design, the structural seismic design, the foundation design and the concrete durability design were mainly introduced for Zhaoqing New District Sports Center. Effective measures in aspects of the design, material and construction were taken to solve the problems of super-long individual structure, temperature stress and concrete shrinkage stress. The calculation results of the lower concrete structure and the roof steel structure can meet the requirements of the specifications.

Keywords:Zhaoqing New District Sports Center; suspendome; foundation design; cantilever steel box girder; durability
