ultimate limit states design of concrete railway sleepers

Ultimate limit states design of concrete railway sleepers ...

Aug 03, 2012  Concrete sleeper design is still based on limiting stresses but is widely perceived by track engineers to lead to untapped reserves of strength in the sleepers. Limit design is a more rational philosophy, especially where it is based on the ultimate dynamic capacity of the concrete sleepers. The paper describes the development of equations and ...

The states of a concrete sleeper can be divided into the following limit states (Leong, 2007; Kaewunruen et al., 2012, 2014). Ultimate Limit State. The ultimate limit state is caused by a single one-off event, such as a severe wheel flat or derailment accident, which generates an extremely high load, capable of causing the concrete sleeper to fail.
