The present work outlines an original numerical modelization approach for Moving Load (ML) beam problems, by a dedicated object-oriented C++ parallel computing FEM implementation, with the purposes of performing efficient numerical analyses resolving the complete dynamic response of beams under the effect of a high-velocity ML. Alongside, main framing state-of-the-art reviews are attempted, on the principal involved issues of: ML context and physical description, numerical FEM modelization, parallel computing implementation. Running ML example cases are explored, for a (long) finite beam on a (visco)elastic foundation and for a continuous beam of a historic railway iron bridge, with per se interesting engineering outcomes. The contribution may serve as a guideline paradigm to readers that may be novel to the treated topics, though motivated in adventuring in the computational challenges involved in the present mechanical research context.

本工作概述了通过专用的面向对象的C ++并行计算FEM实现的运动荷载（ML）梁问题的原始数值建模方法，目的是执行有效的数值分析，以解决梁在力的作用下的完整动态响应。高速ML。同时，尝试对主要框架的最新技术进行审查，涉及的主要问题包括：机器学习上下文和物理描述，数值有限元建模，并行计算实现。探索了运行ML的示例案例，研究了（粘）弹性地基上的（长）有限梁和历史悠久的铁路铁桥的连续梁，并得出了有趣的工程成果。该贡献可以作为读者的指导范式，这些范式对于所处理的主题可能是新颖的，
