The protective door, in the tunnel between two metro stations, plays a very important role. Traditionally, it is made by steel. However, the steel doors are easy to corrode in the dark and humid environment, which leads the potential risk. With the advantages of lightweight, high-strength, corrosion-resistant, the basalt fibre-reinforced polymer (BFRP) protective doors have been used in protection projects recently. In the metro tunnel, the train-induced wind pressure will cause effects on the door, such as vibration, even fatigue issues. In this paper, a new type of BFRP protective door was setup by ABAQUS, the responses under the train-induced wind pressure were investigated. In addition, the fatigue issues were studied. The simulation results show that the BFRP protective door is always keep in elastic range when the train passing with the normal speed. S-N Curve method was used to both the BFRP and steel parts for judging the fatigue issues. It shows that there is no fatigue concern for the new BFRP protective door during its design life-cycle of 50 years.
