Abstract

In this study, the reliability of continuous two-span bridge girder subjected to random vehicular loads is analyzed in the space domain as well as in the time domain. First, by the use of the results of the statistical analysis of randomly space-varying vehicular loads which have been already reported by the authors, the probabilistic characteristics of bending moment and the reliability of bridge girder in the space domain are analytically evaluated. Second, the distribution of the maximum bending moments for the lifetime domain are evaluated. The design values of bending moment are calculated for prescribed values of failure probability of girder bridge.
