Masonry structures comprise a significant portion of the historical building stock all over the world. Previous studies have clearly pointed out that unreinforced masonry buildings are vulnerable against extreme loading conditions, such as seismic actions. Therefore, strengthening is inevitable in most cases for historical masonry to withstand severe loads. In this paper, the efficiency of fabric reinforced cementitious matrix is investigated experimentally by using diagonal tension tests. Fourteen wallets with a nominal size of 750x750x235 mm were produced with using solid clay bricks and a low-strength mortar. The bricks were collected from the structural walls of an early-20th century building under restoration. The low-strength mortar represents the historical mortar commonly used in similar historical brick masonry buildings located in Istanbul, Turkey. By testing the specimens under monotonic diagonal compression loads, the effects of different types of plasters on the wallet surface, varying types of fibers used in textile reinforcement and anchors used for the connection between FRCM and substrate are investigated. Although the wallet samples have inherent shortcomings in representing overall component response accurately, still the qualitative findings are enlightening the effectiveness of the FRCM system by increasing shear strength, stiffness (shear modulus) and dissipated energy of the masonry wallets. The strengthened specimens were failed due to shear sliding along a bed joint and/or by a stair-shaped separation while the refence specimens were failed due to the splitting of the specimen into two parts in the stair-stepped shape and a slipping through a bed joint.

砖石结构在世界范围内占历史建筑存量的很大一部分。先前的研究清楚地指出，未加固的砖石建筑很容易受到极端荷载条件的影响，例如地震作用。因此，在大多数情况下，对于历史悠久的砌体来说，要承受严峻的荷载是不可避免的。本文通过对角拉伸试验，对织物增强水泥基的效率进行了实验研究。使用实心粘土砖和低强度砂浆生产了14个标称尺寸为750x750x235 mm的钱包。这些砖块是从20世纪初的建筑物的结构墙中收集的，这些建筑物正在修复中。低强度砂浆代表在土耳其伊斯坦布尔的类似历史砖石建筑中常用的历史砂浆。通过在单调对角线压缩载荷下测试样品，研究了不同类型的灰泥在皮夹表面，织物增强中使用的不同类型的纤维以及FRCM与基底之间的连接所使用的锚钉的影响。尽管钱包样本在准确表示整体组件响应方面存在固有的缺陷，但定性发现仍通过增加砌体钱包的剪切强度，刚度（剪切模量）和耗散能量来启发FRCM系统的有效性。
