design of prestressed concrete sleepers ppt

Nowadays, prestressed concrete is the most common type used in railway sleeper because of its good structural performance. The main duties of sleeper are to distribute the wheel load to the formation and keep the rail gauge. Most of current design codes for sleepers design techniques rely on allowable stresses and material strength. Get Price

Design of Prestressed Concrete Sleepers - Global Railway ...

28.07.2006  In the USA, design of prestressed-concrete sleepers is based on Chapter 30, Part 4 of the AREMA specification “Concrete Ties”, in the version dated 2003. Here as well, the specification calculates a design moment that the sleeper must assume without cracking. The difference between AREMA and EN 13230 consists in calculation of the design moments, for
