Railway prestressed concrete sleepers are amongst the vital components of the rail trackrnsuperstructure, and play significant role in providing integrity, and safe operation of therntracks. Due to the combined effect of the weight burden from the train, and the dynamicrnload as a result of the train motion, sleepers are subjected to both static and dynamicrnloading conditions. To achieve the desired service life of railway system, sleepers can berndesigned to carry and transfer the wheel loads from the rails to the track foundation. rnCurrent design philosophy for prestressed concrete sleeper is based on permissible stressrnprinciple taking into account only the static and quasi-static loads, which are unrealisticrnto the actual dynamic loads on tracks. However, there still shortcomings when viewedrnfrom the limit state design perspective. Henceforth, limit state function needs to bernincluded in the current design approach as an improvement. There is a need to improvernthe current understanding of the design of prestressed concrete sleepers by reliabilityrnbased design method by formulating limit state function. The limit state function dependsrnon reliability index, and load and resistance factors determined through calibration basedrnon available statistical or scholastic data. rnThis paper, tries to follow the ultimate limit state design approach for axial, flexure, andrnshear design of sleeper by taking into account the compressive and tensile stresses atrnboth initial and final stages of concrete and prestress wires.
