Research conclusions ： As a new type of architecture of railway traffic，no-platform-column canopies have many characteristics different from general railway architectures, so there is still room for improvement in its the structure style，design theory and design method through more practice. The difference from general steel structure is that no col-umn bracings are used for no-platform-column canopy，and the structure should be formed by longitudinal and trans?verse rigid frame as much as possible to improve the structured lateral stiffness and enhance the bracings in roof system to improve the whole performance.
