TL;DR: In this article, a comparison of the aerodynamic loads and corresponding traffic safety of both windproof facilities when the high-speed train (HST) passes through them under crosswind conditions is conducted.

TL;DR: It is shown that the proposed MTS of time integration method is accurate and computationally more efficient than using a uniform time-step for the entire TTBS.

TL;DR: The proposed MTS method is accurate and computationally more efficient than using a uniform time-step for the train-track-bridge coupled system and validated by comparing the numerical results with field measurement data of a cable-stayed bridge.

TL;DR: In this paper, the authors proposed an approach for aerodynamic loads in which the carriage surface is divided into segments in longitudinal and circumferential directions to obtain the real-life time history of aerodynamic load and flow field.

TL;DR: In this paper, an efficient and robust approach is presented for the prediction of subway train-induced ground vibrations considering random track unevenness. And the influence of the train speed on the ground vibrations is also investigated, in which two types of track structure, namely the direct fixation track and floating slab track, are considered.
