Through a case of aseismic design of a subway station in Shanghai, the calculating result comparison of plane model and spatial model is obtained. It is found that the results of two models are nearly the same. The plane model is recommended as preferred method in aseismic design of the subway station. What’s more, based on the calculating result, it is found that the internal forces of column in seismic status were significantly greater than those in static status. Therefore, the aseismic design of column is necessary.Keywords: aseismic design; subway station;
