Lateral loads cause extensive damage to buildings due to the weakness of bearing out-of-plane un-reinforced masonry (URM) walls. Strengthening URM walls is consequently favored by researchers aiming at achieving building and respective occupant safety. The strengthening of masonry structures with textile reinforced mortar (TRM) or steel-reinforced mortar (SRM) has become prevalent in the last two decades. This study presents an innovative method of strengthening masonry walls using mortar reinforced with high tensile strength steel (HTSS) parallel wires. For the first time, an unprecedented investigation as to the effects of the grooving method improving the load-carrying capacity and failure mechanism of masonry walls under out-of-plane loading was performed. In addition, the parallel wires steel-reinforce mortar (PW-SRM) was compared with the textile-reinforced mortar (TRM) reinforcement method. Nine walls with dimensions of 1400 × 440 × 100 mm each were reinforced through different techniques and tested under four-point out-of-plane bending. The implications of the number of glass textiles with open mesh layers, one-sided and two-sided reinforcement, engineered cementitious composites (ECC), grooves on the masonry substrate, and, the volume of HTSS wires in increasing out-of-plane loading were compared and discussed. The findings demonstrated that the best performance is related to the specimens reinforced by the PW-SRM method. Similarly, the amount of out-of-plane load-bearing capacity and energy absorption increased more than 24 and 5300 times compared to the control specimen, respectively. It was further discovered that the grooving method transferred the tensile stress created in the TRM composite to the depth of the masonry substrate, which enhanced the failure mechanism from debonding to textile rupture and increased the strength by 88% compared to the corresponding specimen without grooves.

由于平面外未加固砌体 (URM) 墙的承重薄弱，横向载荷会对建筑物造成广泛破坏。因此，旨在实现建筑和相应居住者安全的研究人员青睐加强 URM 墙。在过去的二十年里，用纺织增强砂浆 (TRM) 或钢筋砂浆 (SRM) 加固砌体结构已成为普遍现象。本研究提出了一种使用高强度砂浆加固砌体墙的创新方法。抗拉强度钢 (HTSS) 平行线。首次对开槽方法提高面外荷载下砌体墙的承载能力和破坏机制的效果进行了前所未有的研究。此外，将平行线钢筋砂浆（PW-SRM）与纺织增强砂浆（TRM）加固方法进行了比较。通过不同的技术加固了九个尺寸为 1400 × 440 × 100 mm 的墙壁，并在四点平面外弯曲下进行了测试。具有开放网状层、单面和双面增强、工程水泥复合材料(ECC)、砌体基板上的凹槽以及 HTSS 线在平面外载荷增加时的体积进行了比较和讨论。研究结果表明，最佳性能与 PW-SRM 方法增强的试样有关。同样，与对照样品相比，平面外承载能力和能量吸收量分别增加了 24 倍和 5300 倍以上。进一步发现，开槽方法将 TRM 复合材料中产生的拉应力转移到砌体基材的深度，这增强了从脱粘到织物断裂的破坏机制，与没有凹槽的相应试样相比，强度提高了 88%。
