This paper presents a novel ductile carbon fiber reinforced polymer (CFRP) anchor system, which has been designed to ensure a controlled high capacity. The response of the anchor system was hypothesized tailorable by adding a ductile mechanism as a part of the anchor system. Three test batches, totaling 43 tests, provide the basis for a functionality sensitivity analysis and thus a threshold basis for tailoring the ductile mechanism response. The response of these were predicted using FE-simulation of three different ductility mechanism configurations and verified by tested. The tensile capacities of the final modified anchor reached a mean value of 2986 MPa, based on tests ranging from 2875 MPa to 3229 MPa. The ductile mechanism provided the intended response to the tensile behavior. An initial elastic regime with a tailored yielding regime initiation at 2330 MPa was reached, with a post elastic stage which enabled utilization of the full anchor capacity. An excellent consistency in the results was thus obtained with large elongations at a high tension magnitude. Consequently, the results furthermore enabled change of failure mode from brittle to ductile.

本文提出了一种新颖的可延展碳纤维增强聚合物（CFRP）锚固系统，其设计旨在确保可控的高容量。假设通过添加延性机制作为锚固系统的一部分，可以调整锚固系统的响应。三个测试批次（总共43个测试）为功能敏感性分析提供了基础，因此为定制延性机制响应提供了阈值基础。使用三种不同延展性机制配置的有限元模拟来预测这些响应，并通过测试进行验证。根据2875 MPa至3229 MPa范围内的测试，最终改性锚的抗拉强度达到平均值2986 MPa。韧性机制提供了对拉伸行为的预期响应。达到了初始弹性状态，并在2330 MPa下采用量身定制的屈服状态，而后弹性状态则可以利用全部锚固能力。因此，在高张力下以较大的伸长率获得了极好的结果一致性。因此，结果进一步使失效模式从脆性变为延性。
