Abstract：Research purposes ： With the development of the railway construction，more and more no-platform - column canopies are used in railway stations. This paper analyzes the characteristics and design method of no - platform - column canopy, studies the main influencing factors，design theories and test analysis for the structural form selection of no - platform - column canopy and puts forward the issues for caution in design.
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.
