Finite Element Analysis of a Precast Fibre Reinforced Concrete Track Slab

Abstract

In this article a macro synthetic fibre reinforced precast concrete track slab’s design process will be presented. The analysis was done with using advanced finite element software called ATENA (Cervenka et al. 2013). Beside the static loads, the precast slab was also checked for dynamic and fatigue loads. The structure was verified for early ages, for de-moulding, rotating, lifting and for transport as well. With the analysis a necessary fibre dosage was determined. After the design AECOM prepared a real scale test for two full slabs. During the test the displacements were measured on different places with using geophones. Finite element model of the test was made with all the details of the real scale test. The results from the tests and from the finite element models were close to each other in every checked case.
