1. 鋼結構工程施工總體方案
1.1 鋼結構工程概況
 主看臺
主看臺鋼屋蓋系統縱向全長約400米；大挑檐立柱處高度約33米；屋蓋結構的懸臂鋼梁最高達42米。上部屋蓋系統為鋼支撐水平梁布置及鋼輕質屋面，下部主要為砼框架結構及階梯看臺。
 新聞中心和空中餐廳
新聞中心和空中餐廳作為主看臺縱向端部的對稱結構。下部結構在看臺F軸一側以砼電梯井筒為主的砼框架，另一側A軸處為行政管理塔和比賽控制塔。上部結構沿建筑物縱向設兩道大噸位的魚腹式巨型桁架，桁架腹桿采用KT型布置，二桁架之間設30米長工字鋼連系梁。魚腹式桁架長約138米，安裝高度為45米不到。、
 副看臺
副看臺共有兩座，每座總長約300米。下部為看臺砼框架；上部每座看臺由13杷鋼結構單柱、橢圓形鋼骨傘塔高低布置。傘塔頂標高約35米不到。
 其它鋼結構單體
其它鋼結構單體主要為單層輕鋼結構，呈現小、輕、散的布置特征。單體項目
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
