When trains pass in stations at high speed, large air pressure variations occur. The members composing station facilities are exposed to the pressure variations repeatedly, therefore it is expected that the deterioration of members will be accelerated. In the future, if the train speed is increased higher, the pressure variations will be larger. Accordingly, it will become more necessary to make effort to ensure the structural safety of stations. For this reason, we developed calculation equations of the pressure variations based on the results of field measurements and model tests, and furthermore we proposed prediction methods for response deformation and evaluation method of fatigue strength of members exposed to the pressure variations.
