Its canopy structure system engmeering, which first adopted of alphabet "A" tower column and character "I" overhung beam to form the spatial structure system. Tlus paper probes into Beijing South Station selection principle and features in the new structure system of the canopy, and the detailed analysis ofits structure including static analysis, seismic analysis, the overall stability analysis and calculation of the length of the components. Studies show that the new structure of Beijing South Station system not only meets the security requirements under the static load combination, but also has good anti-seismic effect. It is a kind of economic, safe, efficient space structure.
