Bridge bearings experience numerous small-amplitude displacements under environmental loads.
The continuous cyclic accumulations of these small-amplitude displacements will result in severe wear on the poly-tetra-fluoro-ethylene (PTFE) plates in the bridge bearings, which seriously endangers the service life of bearings.
Traditional method directly uses the linear wear rate of cumulative displacements in a short period to evaluate the wearing life, but the linear wear rate only in a short period such as several days may not represent the characteristics in the whole bridge service life.
Hence, this research takes the spherical steel bearings of the Nanjing Dashengguan Yangtze River Bridge as a study object.
The cumulative dynamic displacement (CDD) under the action of a single train and the cumulative bearing travel (CBT) under the continual actions of many trains are studied using the monitored longitudinal displacement data from spherical steel bearings.
Furthermore, the probability statistics and the Monte Carlo sampling simulation for CDD are studied, and the safety evaluation method for bearing wear life in the real environment is proposed using a reliability index regarding the failure probability of monitored CBT over the wear limit during service lifetime.
In addition, safety evaluation on the bearing wear life was performed to assess the condition of spherical steel bearings in the real service environment.
The results can provide an important reference for analysis on the bearing wear life of long-span railway bridge structures.
