One of the most frequent and catastrophic problems encountered in reinforced concrete (RC) structures is failure due to shear deficiency in RC structures, especially in RC beams. Thus, in the scope of this experimental study, the effectiveness of using prefabricated ultra-high performance fiber-reinforced concrete (UHPFRC) laminates in the form of plate or strip for shear strengthening was investigated. The change in the plate thicknesses is the first variable of the test program studied herein. Besides, two different application methods were also tested to ensure which can be preferred for shear strengthening with UHPFRC plates; bonding with epoxy, and the use of anchorages. Moreover, as an innovative method, the application of UHPFRC in the form of strip was also investigated. Test results showed that by using UHPFRC laminate as a shear strengthening material; shear strength can be increased by 26% to 47%. Moreover, it is possible to convert behavior from catastrophic shear failure to flexural behavior with the help of UHPFRC laminates. It has been determined that the use of UHPFRC in the strip form helps to increase the load-bearing capacity the most, while the use of anchorage as the bonding method of plates improves the behavior markedly.

钢筋混凝土（RC）结构中遇到的最常见且灾难性的问题之一是由于RC结构（尤其是RC梁）中的剪切不足而导致的破坏。因此，在本实验研究的范围内，研究了使用预制的板或条形式的超高性能纤维增强混凝土（UHPFRC）层压板进行剪切增强的有效性。板厚度的变化是本文研究的测试程序的第一个变量。此外，还测试了两种不同的应用方法，以确保在使用UHPFRC板进行剪切增强时可以优先选择哪种方法；与环氧树脂粘合，并使用固定装置。此外，作为一种创新方法，还研究了带状UHPFRC的应用。试验结果表明，采用UHPFRC层压板作为剪切增强材料；剪切强度可以提高26％至47％。此外，借助UHPFRC层压板，可以将行为从灾难性的剪切破坏转变为弯曲行为。已经确定，条形形式的UHPFRC的使用有助于最大程度地提高承重能力，而锚固作为板的粘结方法的使用则可以显着改善其性能。
