Masonry walls exhibit low tensile strength and high material heterogeneity, which makes them especially vulnerable against cyclic loading conditions, such as those typical in earthquakes. This paper presents the experimental results obtained from tests on three masonry walls reinforced with textile reinforced mortar (TRM) materials subjected to in-plane cyclic loading. These full-scale masonry walls were tested in the LARGE laboratory at the University of Alicante (Alicante, Spain). The walls had been built using a traditional construction technique, with solid clay bricks layered with lime mortar. One specimen was tested and damaged by in-plane cyclic loading and was subsequently strengthened by a vertical layer of TRM with an overlapping of 200 mm. It was then tested again until failure in a second test. In addition, another undamaged specimen had been previously reinforced with the same TRM technique and tested until failure, thus providing a third test. A network of sensors and digital image correlation systems were used to monitor displacements and crack patterns. The comparison between these experimental results made it possible to assess the effectiveness of TRM in restoring the structural integrity of damaged masonry walls and almost doubling their load-bearing capacity under cyclic loads. Conclusions obtained here provide valuable information to the scientific community, architects and structural engineers about the strengthening and repair of severely damaged masonry walls.

砌体墙的抗拉强度低且材料异质性高，这使得它们特别容易受到循环荷载条件的影响，例如地震中的典型情况。本文介绍了通过在面内循环荷载作用下用纤维增强砂浆（TRM）材料增强的三层砌体墙进行试验获得的实验结果。这些全尺寸的砌体墙在阿利坎特大学（西班牙阿利坎特）的大型实验室中进行了测试。墙壁是使用传统的施工技术建造的，坚固的粘土砖上铺有石灰砂浆。测试了一个标本，并通过面内循环载荷对其进行了损坏，随后通过垂直TRM层（重叠200毫米）进行了加固。然后再次进行测试，直到第二次测试失败。此外，另一个未损坏的样本先前已使用相同的TRM技术进行了加固，并进行了测试直至失效，从而提供了第三次测试。传感器和数字图像相关系统组成的网络用于监测位移和裂缝模式。这些实验结果之间的比较使我们有可能评估TRM在恢复损坏的砌体墙的结构完整性以及在循环荷载下的承载能力几乎翻倍的有效性。此处得出的结论可为科学界，建筑师和结构工程师提供有关加固和修复严重损坏的砌体墙的宝贵信息。传感器和数字图像相关系统组成的网络用于监测位移和裂缝模式。这些实验结果之间的比较使我们有可能评估TRM在恢复损坏的砌体墙的结构完整性以及在循环荷载下的承载能力几乎翻倍的有效性。此处得出的结论可为科学界，建筑师和结构工程师提供有关加固和修复严重损坏的砌体墙的宝贵信息。传感器和数字图像相关系统组成的网络用于监测位移和裂缝模式。这些实验结果之间的比较使我们有可能评估TRM在恢复损坏的砌体墙的结构完整性以及在循环荷载下的承载能力几乎翻倍的有效性。此处得出的结论可为科学界，建筑师和结构工程师提供有关加固和修复严重损坏的砌体墙的宝贵信息。
