The shift to more sustainable mobility systems is one of the major priorities to accomplish the goals established by the European Green Deal to make Europe the first climate neutral continent by 2050. Railways plays a crucial role in this regard, but it is essential to enhance the current resilience and capacity of the network, in particular from lifeline structures, such as bridges.Within this regard, several open points affecting the current INF TSI and described in the ERA Technical Note are yet to be closed, namely those related to the Dynamic Train Categories previously specified in EN15228:2015 and the limits of validity of the static compatibility checks currently stipulated EN15228:2021, the accuracy of the current dynamic amplification factors and damping values for railway bridges proposed in EN1991 2 (2003) and the validity of the deck acceleration limits imposed by EN1990-Annex A2 (2005) in both new and existing bridges.InBridge4EU aims to answer these points through the formulation of an enhanced and harmonized method to assess the European dynamic interface between railway bridges and rolling stock. The outcomes of this project will provide solid background to the guidance being drafted within the CEN/TC250/SC1 special group DIBRST for dynamics of bridges. Finally, as a consequence, the economic outcomes of changing any of the aforementioned criteria/parameters/methodologies in the current European railway bridge landscape will be carefully assessed. All the research carried out in InBridge4EU will converge on recommendations to ERA and CEN for revising and updating the current version of the TSIs and Eurocodes. Advanced numerical modelling and dynamic analyses of both bridge and railway vehicles, together with the development of extensive databases of bridge and rolling stock data obtained from the different partners of the consortium, will contribute to the successful achievement of the project’s objectives.

转向更可持续的移动系统是实现欧洲绿色协议确立的目标的主要优先事项之一，该目标旨在到2050年使欧洲成为第一个气候中立大陆。在这方面，铁路发挥着至关重要的作用，但必须提高网络的当前弹性和能力，特别是从桥梁等生命线结构。在这方面，影响当前INF TSI的几个开放点尚未关闭，即与EN15228：2015中先前规定的动态列车类别有关的开放点，以及当前规定的静态兼容性检查的有效性限制，铁路桥梁现有动力放大系数和阻尼值的准确性，以及EN1990-附录A2(2005)规定的桥面加速度限值在新桥和既有桥梁中的有效性。该项目的成果将为CEN/TC250/SC1桥梁动力学特别小组DIBRST正在起草的指南提供坚实的背景。最后，因此，将仔细评估在当前欧洲铁路桥景观中改变上述任何标准/参数/方法的经济结果。在InBridge4EU进行的所有研究都将集中于向ERA和CEN提出的修订和更新当前版本的TSIS和欧洲代码的建议。对桥梁和铁路车辆进行先进的数值建模和动态分析，以及开发从该联盟的不同伙伴那里获得的桥梁和车辆数据的广泛数据库，将有助于成功实现该项目的目标。
