  7. Abstract:
  8. A brief overview of the proposed research, its aims, engineering relevance and applications Underground space has long been exploited through the history to fulfill different human necessities. Underground facilities built in areas subject to earthquake activity must withstand both seismic and static loads. Some underground structures have experienced significant damage in recent large earthquakes. Tehran is located in seismic zone and investigation and research on the subject has significant role in design and construction of underground spaces for earthquake loads. Underground structures are complex structures which consist of different parts Such as passage way and platform space. Passage way in subway station connects the platform space to ticket hall. The material and geometrical parameters have an important role in behavior of the structure in response to the dynamic loads. In the present state of the analysis and design of underground station, generally the effects of some of these parameters and design for dynamic loads have been ignored. This research conducts the effect of parameters by analyzing and simulating the different direction of applying earthquake for underground structures includes station and stair. Behavior of the passage way structure in response to the dynamic loads in underground subway station will be investigated and the influence of parameters will be assessed. Generated stresses and displacements will be sketch in critical points. The results of the research can be used in stability analysis of these structures in earthquake
