2020年优先方案能够为了解高性能混凝土在第一个资助期(FP I)期间的疲劳行为作出国际上可见的贡献。这一点在国际会议的优先计划具体会议上表现得尤为明显，这些会议产生了积极的共鸣，并产生了最佳论文和最佳青年研究员奖。在第二个资助期(FP II)，工作重点将放在进一步调查损坏机制和复杂的周期性加载模式对操作负载的影响上。为了达到这些目的，新的补充测量技术和记录高精度测量数据是必要的。这些将作为与实验一起进一步改进的数值模型的校准基础。实验调查和数值模拟的中心挑战在于超越相关尺度从微观到宏观的范围，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。通过FP I收集的数据，产生了一个重要的数据库，现在可进一步用于FP II。所有项目都将整合到一个紧密的网络中(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)加以处理。为此目的，除其他外，将在现有(可能经过专题调整的)工作组的基础上，从监督技术立场开始协调合作。通过在第一方案中提供两个参考混凝土，为对不同设施产生的结果进行合格的比较奠定了基础。此外，在FP I(部分由BAM支持)举行了会议，目的是最大限度地利用高度现代化的计量方法(待FP II继续)。为了提高数值模拟方法的可比性，已经在FP I中启动了多个基准测试，FP II将加强这些测试。内容协调将与中央项目的科学工作密切相关，该项目的目标是检测和描述休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方，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央项目有助于增加整个优先项目的科学产出，并为在混凝土疲劳领域实现有效的实验-虚拟实验室做出重要贡献。

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.
