In-plane strength of masonry walls is affected by the resistant mechanisms activated in the walls, i.e., related to flexural or shear behavior. The latter one can occur in the walls according to different failure modes depending on both mortar and unit strengths and on the type of assembling, i.e., 'regular' or 'irregular' texture. In this paper, a critical review of the existing design formulations for the in-plane strength of masonry walls is firstly presented, with important information on the achievable failure modes depending on the geometrical and mechanical features of the masonry fabric. Then, experimental tests are collected from the literature and a comparison between theoretical and experimental results is carried out. The presented analyses are aimed to highlight the differences between the existing formulations and to identify the most suitable ones.
砌体墙的面内强度受墙体中激活的抵抗机制影响，即与弯曲或剪切行为相关。根据砂浆和砌块强度以及组装类型（即“规则”或“不规则”纹理），后者可能以不同的破坏模式出现在墙体中。本文首先对现有的砌体墙面内强度设计公式进行了批判性综述，并给出了根据砌体结构的几何和力学特征可能出现的破坏模式的重要信息。然后，从文献中收集了实验测试数据，并对理论结果和实验结果进行了比较。所进行的分析旨在突出现有公式之间的差异，并确定最合适的公式。
