Abstract
The safety of supporting structures for high-speed trains has motivated many researchers to develop an effective method for reliability analysis of the structure as a whole. In this study, a unitless model for system limit state function is developed, which enables the system reliability analysis of the CRTS II track slab on viaduct with multiple failure modes. The method of moments is employed to determine the system reliability, and the influences of important variables on the system reliability of the track slab are investigated. It is found that the reliability of the CRTS II track slab would be overestimated if only individual failure modes are considered independently, which vindicates the importance to conduct system reliability analysis for CRTS II track slab. It is also found that the randomness of the number of load cycles significantly affects the system reliability of the track slab. The merit of the developed unitless model for system limit state function is its facilitation of the efficient and accurate analysis of system reliability for the CRTS II track slab with no conditions and constraints.
