Abstract：The paper has analyzed the mid-column section and come up with the idea of displacement response which was applied on rigorous component model. Three-dimensional elastic-plastic time history analysis of subway station mid-column under earthquake action was achiered. The subway station was submitted to sectional elastic-plastic time history analysis,and relative displacement time history response of both ends of the mid-column was obtained. Then relative displacement time history response was applied to the both ends of elaborate model of mid-column to achieve the time history response in the earthquake action. The results showed that mid-column generated a large-scale plastic zone when rare earthquake was applied at 3.94s. In addition, the concrete of the end portion of mid-column failed, even fell off, and the plastic hinge fully formed at 4.6s and 5.0s. The results of refinement simulation of mid-column was in accordance with that of section simulation of subway station. Moreover it was very similar to the actual earthquake damage.
