Enhanced INterfaces and train categories FOR dynamic compatibility assessment of EUropean railway BRIDGEs

向更可持续的交通系统的转变是实现《欧洲绿色协议》（European Green Deal）所确立的目标的主要优先事项之一，该目标是到2050年使欧洲成为第一个气候中立的大陆。铁路在这方面发挥着至关重要的作用，但必须提高铁路网络目前的复原力和能力，特别是桥梁等生命线结构的复原力和能力。在这方面，影响当前INF TSI和ERA技术说明中描述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和目前规定的EN15228:2021中规定的静态兼容性检查的有效性限制有关的问题。EN1991 - 2（2003）中提出的铁路桥梁当前动力放大系数和阻尼值的准确性，以及en1990 -附件A2（2005）对新建和现有桥梁施加的桥面加速度限制的有效性。InBridge4EU旨在通过制定一种增强和协调的方法来评估欧洲铁路桥梁和机车车辆之间的动态界面，从而回答这些问题。该项目的成果将为CEN/TC250/SC1 DIBRST桥梁动力学特别小组正在起草的指南提供坚实的背景。最后，因此，在当前的欧洲铁路桥景观中改变上述任何标准/参数/方法的经济结果将被仔细评估。在InBridge4EU中进行的所有研究将集中于向ERA和CEN提出修改和更新当前版本的tsi和欧洲规范的建议。先进的桥梁和铁路车辆的数值模拟和动力分析，以及从联盟的不同合作伙伴那里获得的桥梁和铁路车辆数据的广泛数据库的发展，将有助于成功实现项目的目标。

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.
