A newly developed computer program called DAB-TIP is presented for analyzing the dynamic interaction between trains and bridges. By modeling a train as a sequence of moving loads or sprung masses considering the suspension effects, the impact response of the bridge caused by the moving action of the train and the riding comfort of the car bodies that constitute the train are studied. Using this program, one is able to investigate the various dynamic behaviors of the train-bridge interaction system. An example containing a bridge simply supported at its two ends subject to the action of high speed trains is prepared to illustrate the capability of the program.
