Vehicle-Bridge Dynamic Interaction Analysis Of Elevated Railway Station

Elevated railway stations is a new type of structure, so it is necessary to ensure the safety and comfort of the station structure. There are two main contents in this dissertation, one is analysis of the dynamic response under vehicle load with constant velocity, and the other is analysis of dynamic longitudinal response of elevated station under braking force.Firstly, the historic and current reseaches in the field of train-structure dynamic interaction are reviewed on related references. Then it is calculated that response of the New Guangzhou Railway Station when the Pioneer Train passing under constant velocity by DRV8.5. The vibration of waiting room floor in the New Guangzhou Railway Station is between the limitations of shopping centre and pedestrian bridge.Secondly, according to NEWMARK-β, the software DRSBF is programed in MATLAB to calculate the longitudinal response of the Wuhan Railway Station under braking forces. The Pioneer Train and the SS8 Train are studied to brake at different speeds and positions. Three conclutsions can be drawn from the calculation:(a) The response of structure under the SS8 Train is bigger than under the Pioneer Train;(b) The higher speed at which the train (both the Pioneer and SS8) start to brake,the smaller response of structure;(c) The responses fo nodes of the structure which are far away from the train are close to zero.
