Abstract：Research purposes: After research on the main body of no-platform-column canopies (the first in China) with large span and long-suspending-extending structure in Beijing railway station, the key problem in the period of canopy construction is solved, and the safety and credibility of main body of canopies are guaranteed.
Research methods: The optional computing data of structure is made certain by colligating analysis on the project and integrating the result researched by the others of this subject in China. 3D3S software which is steel structural calculating system is used by calculating and checking.
Research Conclusions: Under the complicated existing condition in the station, the section size of supporting columns and the structure height being limited, the columns are located among the tracks for the first time and some innovated design and technology are adopted, such as large span over-passing two platforms, long-suspending-extending structure and so on. Thus, it is realized that there are no columns on all platforms. This research resolved many difficulties in engineering process. On the other hand, it is indicated that large span and steel structure is the same with construction of no-platform-column canopies.
