A Numerical Study of the Influence of Prestressing Reinforcement Position on Sleeper Response

Popis výsledku v původním jazyce

A numerical study of the structural response of the prestressed monoblock railway sleepers used on Czech railway tracks is presented. The build quality of prestressed railway sleepers is assessed using three-point bending tests as stipulated by Europe-an Standards. Two sleeper cross-sections are evaluated with respect to static load-ing. The tests are modelled herein using ATENA nonlinear finite element method (FEM) software. This programme enables the realistic estimation of failure load, pre/postpeak behaviour and crack pattern using non-linear fracture mechanics meth-ods as well as damage and plasticity models. The main purpose of this study is to quantify the influence of prestressing reinforcement position on sleeper response during evaluative tests. A comparison of the simulation results with experimental data is also performed.
