Abstract Research purposes: The flame structure is farely used for the main—linerailway bridge．This paper studies the rationality of application of frame structure system in the main—-line bridge in the Hongqiao Railway Station in Shanghai with the train speed of 200 km／h．
Research conclusions: In this paper，the safety of structure，the safety and stability of train and the comfortableness of passenger are fully evaluated with the train—structure coupling dynamic analyse method．The analyse results show when the train rails at a speed of at least 200 km／h over the main—line bridge with frame structure in Hongqiao Railway Station，the safety of structure，the safety and stability of train and the comfortableness of passengem meet the design demand．As a result，in order to satisfy the requirement of integration of building function with the building style，it is suggested that the frame structure system is applied in the main—line railway bridge when the building and bridge are integrated in the railway station．It is also suggested that the train—structure coupling dynamic analysis should be made on premise of meeting the requirement of static calculation．
