An empirical study of masonry wall repair is presented in the current work. The textile reinforced mortar used for repair comprises a stainless-steel grid embedded in a cement matrix. This composite was applied locally and along the cracks, on a previously damaged unreinforced masonry wall. The repaired wall was then subjected to a pushover load until its maximal strength was reached. Results of the damaged and repaired configurations indicate that recovery, and even a gain of initial stiffness and strength, was achieved. Finite-element simulations of the unreinforced and repaired walls were then carried out with an innovative approach to the repair modelling. The main features of the experimental Unreinforced Masonry Wall were reproduced. Finally, simulations of the repaired wall were generated to assess the gain in strength for several degrees of wall damage. Using this model, the crack patterns were investigated and the effects of different repair configurations are discussed.

在目前的工作中介绍了砌体墙修复的实证研究。用于修复的织物增强砂浆包括嵌入水泥基质中的不锈钢网格。这种复合材料被局部和沿着裂缝施加在先前损坏的未加固砖石墙上。然后对修复后的墙施加推覆载荷，直到达到其最大强度。损坏和修复配置的结果表明实现了恢复，甚至获得了初始刚度和强度。然后使用创新的修复建模方法对未加固和修复的墙壁进行有限元模拟。再现了实验性未加固砌体墙的主要特征。最后，对修复后的墙壁进行模拟，以评估不同程度的墙壁损坏的强度增益。使用该模型，研究了裂纹模式并讨论了不同修复配置的影响。
