Abstract Abstract: Research purposes: The hierarchical structure of large railway station compared to common station is more complex. Generally it is divided into level bearing rail, elevated level and roof level. How to select the reasonable load values and seismic performance objectives combined with its importance and function became the problems to be solved urgently. On the basis of the example of one certain railway station，the analysis and computations of steel reinforced concrete beam affected by factors of performance - based seismic design three level and frequent earthquake under fire engine load and bus load are finished in the paper, and the effect of stirrup under different web opening are discussed. Research conclusions ： (1 ) The calculation condition of steel reinforced concrete beam is complex, and the internal force calculation condition is not necessarily the reinforcement control conditions, so envelope design of structure is necessary. (2)The shear bearing capacity of steel reinforced concrete beam is high, for open hole reinforcement using stiffening rib around the hole or stirrup encryption can satisfy engineering demand. ( 3 ) The research results proposed a new pattern for load determination and calculation methods of railway station，and provided the beneficial references to similar projects.
