TTB-2D: Train-Track-Bridge interaction simulation tool for Matlab

The software TTB-2D simulates the dynamic response of a Train-Track-Bridge system in a 2D representation. The train is represented as a succession of multiple vehicles. The track includes rail irregularities and models the rail, pad, sleeper, ballast, and sub-ballast. The bridge is modelled as a beam in finite element formulation with customizable support conditions, which effectively enables the representation of a wide range of structural configurations. This validated numerical model accounts for the vehicle-infrastructure interaction. This document provides the theoretical background to the modelling and a usage guideline supported by an illustrative example.(c) 2022 The Author(s). Published by Elsevier B.V.
