“…Researchers from Australia, Canada, Japan, and Sweden have also carried out numerical and experimental studies into the responses of prestressed concrete sleepers under impact load, in order to develop the limit states design approach (Wang, 1996;Wakui and Okuda, 1997;Kaewunruen, 2007). Fatigue properties of materials, such as concrete, reinforced steel, and prestressed steel, under fatigue loading are well established (Hanson et al, 1974;CEB-FIP, 1988; American Association of State Highway and Transportation Officials, 1989;CEB-FIP M 90, 1993;EC2, 2005;AS3600, 2009;Japan Society of Civil Engineers, 2010).…”

“…This method relies on the permissible stress of materials and uses a load factor to increase the static axle load to consider dynamic effects (Kaewunruen et al, 2012). Since the permissible stress method does not take into account the dynamic load accurately, while also underestimating the strength of the material, much research has been performed to develop the limit states design approach for concrete sleeper (Wang, 1996;Wakui and Okuda, 1997;Gustavson, 2002). The concept of the limit states design is based on a probabilistic model of the resistance and loads factors and it takes into account a reliable distribution statistic of loads and resistance (Remennikov et al, 2011).…”

Concrete sleepers are one of the most important applications of a railway track system. Researchers have previously studied the impact load characteristics and ultimate load carrying capacity of a prestressed sleeper, but research on the fatigue life of prestressed concrete sleepers is limited. Fatigue damage of a prestressed concrete sleeper is mainly due to the accumulation of defects caused by the repeated load of wheel-rail interaction. Fatigue load, fatigue characteristics, and the existing design methods of prestressed concrete sleeper are summarized in this paper. The commonly used fatigue assessment methods of concrete structures are also evaluated. Based on the results of former research, this article presents a convenient fatigue life assessment method for a prestressed concrete sleeper and contrasts with the test results. The insight information gained can be used to evaluate the service performance and predict the fatigue life of the concrete sleeper, as well providing design flexibility and broadening the design principle. The outcome of this study may also improve the rail track maintenance and inspection criteria, in order to establish an appropriate track condition monitoring network in practice.

“…Among them, the impact loads due to the rail joint and the wheel flats tend to be relatively large. In Japan, from the beginning of the development of the PC sleepers, the wheel flats have been recognized as one of the biggest factors of the impact load and studies on the influence of the impact load caused by the wheel flats on PC sleepers have been actively conducted [1]. On the other hand, there have been few studies on the influence of the impact load caused by the rail joint on PC sleepers.…”
