Vliv stáří a únavy betonu na odezvu předpjatých železobetonových pražců: parametrická studie a experiment

Original language description

This paper introduces a study of influence of material parameters of concrete on mechanical response of pre-stressed monoblock railway sleepers used on Czech railway tracks. The influence of selected mechanical/fracture parameters of concrete on structural behaviour of the studied pre-cast structural members is investigated by means of numerical modelling of standardized static loading tests, which are used as a tool for quality control of sleeper?s production according to European Standards for railwayapplications. The tests are numerically simulated using ATENA nonlinear finite element method software. Results of the numerical study are compared with experimental data obtained on sleepers tested after 17 years of traffic service.
