1. Overall plan construction of steel structure
1.1 Steel Structure Overview
 Grandstand
Grandstand steel roof system, total length 400 m vertical; large overhanging pillar Department altitude of about 33 meters; cantilever roof structure up to 42 meters. The upper level roof support system for steel and steel light roof beam arrangement, the lower part of the main frame for the concrete structure and ladder stands.
 information centers and air restaurant
News and vertical air restaurant stands as the end of the main symmetry. Substructure F in the stands with concrete elevator shaft at the side of the concrete framework of the main shaft, the other side of the A axis of the administrative tower and the competition for the control tower. Superstructure along the longitudinal building located two large tonnage of Fish-bellied giant truss, truss belly bar with KT-type layout, located between two 30-meter truss I-beam tie beam. Fish-bellied truss is about 138 meters, the installation height of less than 45 meters. ,
 Deputy Stand
Deputy stands a total of 2, total length of 300 meters per seat. The lower part of the framework for the concrete stands; upper Grandstand from 13 loquat every single column steel, oval-shaped steel tower height umbrella arrangement. Umbrella top of the tower about 35 meters less than elevation.
 Other steel monomer
Other steel monomer mainly single light steel structure, showing small, light, loose arrangement of features. Single Project
