Changes in Material Properties and Damage Mechanism of Plate Ballastless Track Under Fire and High Temperature

Buildings
The service status of rail, fasteners and track slabs is the key determinant of whether the ballastless track is ready for traffic after a fire. The track slab rail support bolt anchoring performance and the shoulder service performance damaged by fire ...

Parallel computing aided analyses of dynamic buckling for railway track infrastructure

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 19, Page 2943-2968, 5 August 2025.
Abstract This paper presents a scalable parallel computing framework for simulating track buckling under dynamic train loads, enabling large‐scale railway track stability analysis. A three‐dimensional (3D) track model is developed using finite element‐based Euler–Bernoulli beam formulations for rails, dynamic force inputs, and nonlinear interactions at
