Concrete sleepers with their elastic fastenings also provide better safeguard for important track parameters, such as, gauge, cross levels form of twist, alignment etc. as compared to other types of sleepers. Of the several types of concrete sleepers in use, survey indicates that a majority of them, as much as 70% are monoblock prestressed

A comparative analysis of the structural behaviour of prestressed concrete sleepers made with high performance concrete (HPC) and high performance recycled aggregate concrete (HPRAC) is presented in this study. Two types of HPRAC sleepers were tested, using 50 and 100% of recycled concrete aggregate (RCA) in replacement of coarse natural aggregates. The RCA employed in this research was

Am trying to model a prestressed concrete sleeper in ansys workbench and planning to use solid65 for concrete and link180 for rebar. Since am new to ansys I''ve started with a simple prestressed beam and through following tutorials been able to model an RC beam but stranded on how to apply prestressing to the rebar in workbench.

Prestressed concrete sleepers are now being increasingly used by most of the railways throughout the world in preference to timber ones because of scarcity of timber and the inherent technical advantages of concrete sleepers for use with long welded tracks carrying heavier axle loads and designed for greater speeds.

Design of prestressed concrete sleepers. The basis for design work for prestressed-concrete sleepers in Europe is EN 13230, valid since October 2002: “Concrete sleepers and bearers.”. A supplement to this standard is UIC 713: “Design of Monoblock Concrete Sleepers,” which provides a design example for a prestressed-concrete sleeper.

Abstract. In this study, analytical study is executed to evaluate loading capacity of a prestressed concrete sleeper (PC sleeper) using numerical analysis models reproducing static loading test and impact load test. Recently, demand for replacements of existing PC sleepers is increasing, and hence surveys of deteriorated PC sleepers and studies
