Method for predicting vibration response of building structure caused by train operation

The invention provides a method for predicting the vibration response of a building structure caused by train operation, and relates to the technical field of rail transit environment vibration prediction.The method comprises the following steps that train dynamics design parameters are obtained, and a train model is established; obtaining track structure design parameters, and establishing a track structure model; establishing a train-track structure model by using the train track contact relationship; obtaining design parameters of a building structure where the train runs, and establishing a building structure model; constructing a train-track structure-building structure coupling model by using the contact condition of the track structure and the building structure; wheel-rail contact force generated by train operation is calculated by considering the influence of track irregularity; and calculating a vibration acceleration time travel curve of the track structure and the building structure.
