英文摘要：

The bleacher of Hangzhou Olympic and International Expo Center main stadium is composite of steel reinforced concrete composite structures, which has characteristics of good ductility, fire prevention and corrosion resistance performance. In this paper, the structure characteristics of the engineering and construction technical difficulties and construction schemes are analyzed, and the deepening of cast steel joint design, ring beam bifurcate V-shaped oblique column and beam installation, complex joint construction simulation, key technology such as reinforced concrete is studied. Engineering practice shows that the construction technology can effectively guarantee the construction quality and construction schedule.
