Abstract: The compression ring of Lusail Stadium consists of 24 segments. Lifting segment by segment, high altitude docking installation method was adopted. Each segment has large size, heavy weight, difficulty in installation, high requirement on welding quality. Based on the difficulties,the installation method and technical requirements are discussed. The results confirm that the technology of the hoisting and installation of the compression ring meet the safety and quality requirements, guarantee the construction progress, and can also offer a reference for the installation works of similar large steel members in other project.

Keywords: stadiums; steel structures;compression ring; hoists;installation
