The Priority Programm 2020 was able to produce an internationally visible contribution towards the understanding of the fatigue behaviour of high-performance concretes over the course of the first funding period (FP I). This became apparent on such occasions as Priority Program specific sessions at international conferences, which resonated positively and yielded awards for Best Paper and Best Young Researcher. In the second funding period (FP II), work will focus on further investigations into the damage mechanisms and on the influence of complex, cyclical loading patterns in terms of operating loads. For these purposes, novel complementary measurement techniques and the recording of highly precise measurement data are necessary. These will serve as the basis for calibration of numerical models refined further alongside with the experiments. The central challenge for the experimental investigations as well as the numerical modelling rests in transcending of the relevant size scales from the microscopic to macroscopic level and this shall be addressed through new experimental and numerical techniques which additionally require a temporal scaling. Through the data gathered in FP I an important data stock has been produced which can now be used further in FP II.All projects will be integrated within a tight network (structural coordination) and content related interfaces between the projects will be addressed through concerted measures of the coordinating project (content coordination). For this purpose a coordinated cooperation will be initiated from a supervisory technical position, inter alia on the basis of existing (an perhaps thematically adjusted) working groups. Through the provision of two reference concretes in FP I a foundation was established for qualified comparisons of results produced at different facilities. Furthermore, meetings in FP I (partly supported by the BAM) took place for the purpose of maximizing the effectiveness of the use of highly modern methods of measurement (to be continued in FP II). For better comparability of the numerical modelling approaches already multiple benchmark-tests were initiated in FP I which will be intensified in FP II. The content coordination is to be carried out in close connection to the scientific works of the central project, which has as its objective to detect and describe the influence of resting periods upon the cyclical degradation behaviour of high-performance concrete. The data gathered therein will be made available to all Priority Project participants for validation and calibration of their respective models. Altogether, the coordinating project and the central project embedded therein contribute to the increase of the scientific output of the entire priority project and additionally deliver an important contribution towards achieving a functioning Experimental-Virtual-Lab in the realm of concrete fatigue.

2020年优先计划能够在第一个资助期（FP I）内为理解高性能混凝土的疲劳行为做出国际可见的贡献。这一点在国际会议上的优先方案专题会议上变得很明显，这些会议产生了积极的反响，并获得了最佳论文奖和最佳青年研究员奖。在第二个供资期（FP II），工作重点将是进一步调查损坏机制以及复杂的周期性加载模式对运行载荷的影响。为此，需要新的补充测量技术和高精度测量数据的记录。这些将作为校准数值模型的基础，并与实验一起进一步完善。实验研究以及数值模拟的核心挑战在于从微观到宏观层面的相关尺寸尺度的超越，这将通过新的实验和数值技术来解决，这些技术还需要时间尺度。所有项目都将纳入一个紧密的网络（结构协调），项目之间与内容有关的接口将通过协调项目的协调措施（内容协调）来解决。为此，将从技术监督的角度，阿利亚是在现有的（也许按主题调整的）工作组的基础上，开展协调合作。通过在FP I中提供两种参考混凝土，为不同设施产生的结果的合格比较奠定了基础。此外，在第一个计划生育方案中举行了会议（部分得到管理局的支持），目的是最大限度地提高使用高度现代化的计量方法的效率（将在第二个计划生育方案中继续进行）。为了使数值模拟方法具有更好的可比性，已经在FP I中启动了多个基准测试，并将在FP II中加强。内容协调将与中心项目的科学工作密切相关，其目标是检测和描述静止期对高性能混凝土周期性退化行为的影响。其中收集的数据将提供给所有优先项目参与者，以验证和校准其各自的模型。总而言之，协调项目和嵌入其中的中心项目有助于增加整个优先项目的科学产出，并为实现混凝土疲劳领域的功能实验虚拟实验室做出重要贡献。
