PSEUDO-DYNAMIC ANALYSIS OF RAILWAY BRIDGES SUBJECTED TO BRAKING FORCES

摘要

The braking force shared by each abutment or pier of a railway bridge is closely related to the stop positions of the train. Considerable numbers of static or dynamic analysis have to be performed to find the most unfavorable position of the train and the maximum displacement response of the considered abutment or pier. The pseudo-dynamic analysis method developed in this paper needs only one time of dynamic evaluation to give an all course static solution of a track-bridge system.
