In this model, you will learn the failure of railway sleepers, concrete structures with reinforced steel cores and evaluate the load-carrying capacity of the pre-stressed concrete sleepers using ABAQUS software.
The sleeper is a fundamental component of the railway track's superstructure. In summary, its primary functions are to support the rails, maintaining the track's axis, and transmit the actions of the vehicle axles to the ballast. These functions necessitate providing the sleeper with a high level of strength, which generally results in a high level of stiffness; however, it is also necessary to have a certain level of elasticity, as it must be able to withstand extremely high impact forces. The application of pre-stressed rebar is intended to improve the durability of sleepers in a railway operating environment subjected to repeated impact loads.
