Original Abstract

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 studied pre-cast structural members is investigated by means of numerical modelling of standartized static loading tests, which are used as a tool for quality control of sleepers production according to European Standards for railway applications. The tests are numerically simulated using nonlinear FEM software ATENA. The aim of work of composite authors is to improve the reliability of railway sleepers by prospective introduction of reasonable changes in the technology of sleepers production.
