Abstract

This paper presents a nonlinear finite element simulation of the top slab-track layer railway designed for high-speed train systems. The study investigates the top slab-track layer previously designed using a conventional reinforced concrete (RC) structure with the new material design based on fiber-reinforced concrete (FRC). This study is the pilot project on using advanced material technology for the slab-track structure. The two fibers that would be used to construct the FRC are the hooked-end steel fiber DRAMIX 3D 65/35 and polypropylene fiber. The volumetric content of both fibers is 2.0%. The basic concrete strength is 50 MPa. In this paper, only one panel of slab-track is being investigated. The panel has a width of 600 mm, a width of 2500 mm, and a thickness of 200 mm. The panel is tested as a simply supported beam with an inverted position to mimic the restraint imposed by the wheel train. The simulation uses an in-house 3DNLFEA package with a multi-surface plasticity model suitable for modeling plain and fiber-reinforced concrete. The simulation found that using fibers can improve the peak load-carrying capacity and enhance the post-peak softening behavior of the slab-track structures.
