and prestressed concrete members. A three-dimen-sional non-linear finite element model of a railway prestressed concrete sleeper was developed using the general purpose finite element analysis package, ANSYS10 [7]. The concrete section was modelled using SOLID65 solid element where the compres-sive crushing of concrete and the concrete cracking

Project Report on PRE-STRESSED CONCRETE RAILWAY SLEEPERS ...

PRE-STRESSED CONCRETE RAILWAY SLEEPERS. ... The bearing area of sleepers below the rail seat and over the ballast should be enough to resist the crushing due to rail seat and crushing of the ballast underneath the sleeper. vi. The sleeper design should be such as to facilitate easy removal and replacement of ballast.

The Complete Beginner's Guide to Indian Rail Sleeper

The sleeper is pre-stressed with 18 high tensile steel (HTS) strands of 3×3mm diameter and 126mm diameter mild steel links. The initial pre-stressing of the steel is 100 kg/cm2. The 28-day crushing strength of the concrete is not less than 525kg.The rail is placed on a grooved 130×130mm rubber pad.

Jul 28, 2006· 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.

(PDF) A review of behaviour of Prestressed concrete sleepers

Prestressed concrete sleepers (PCSs) are the most commonly used type of sleepers. They play an essential role in track performance, behaviour and safety. The focus of the published literature on ...

Modelling the prestress transfer in pre-tensioned concrete ...

concrete beams and railway sleepers [14,15]. The concrete was modelled using 8-node solid elements and truss elements were used to model the prestressing steel. Concrete cracking and crushing were modelled using the concrete damage plasticity model proposed by …

Failure prediction of impact behaviour of self‐compacted ...

Prestressed concrete sleepers often get damaged during derailments. At the time of the derailment, a high-magnitude impact load acts for a short duration of time. ... Cracks at the bottom of the sleepers and B, crushing at the top of sleepers. A typical pattern of the failure of prestressed concrete sleepers can be observed from Figure 5.

Types of concrete sleepers - BrainKart

PCS-12 is the latest type of prestressed concrete (PRC) sleeper for use on BG routes with 52-kg rails and elastic rail clips. For use with 60-kg rails and elastic rail clips, the PCS-14 sleeper has been standardized on Indian Railways. The important dimensions of both of these types of sleepers are shown in Fig. 7.13 and listed as follows.

Performance of Innovative Precast Concrete Sleepers ...

For prestressed GFRP sleepers to be accepted as replacements for defective sleepers made with timber and concrete, they must pass several short- and long-term tests. Full-scale GFRP- and steel-reinforced concrete sleepers were designed, tested, and compared according to the requirements of the American Railway Engineering and Maintenance-of-Way ...
