Original Title

Pravděpodobnostní analýza šířky trhlin předpjatého pražce při kontrolní zkoušce

English Title

Crack width in concrete of prestressed railway sleeper during 4PB test: probabilistic analysis

Type

conference paper

Language

Czech

Original Abstract

Numerical modelling of 4PB test of prestressed railway sleepers using randomization of ATENA nonlinear FEM software and probabilistic simulation software FREET (Feasible Reliability Engineering Efficient Tool) is presented in the paper. This software makes possible to consider input variables of sleeper model as random variables simulated by Latin Hypercube Sampling. The estimations of variability of sleeper response, sensitivity analysis of selected input variables and mainly probabilities of crack occurrence at specific load level are results of this paper.
