The masonry building heritage consists of a large variety of masonry typologies. Often, apparent thick-walls are frequently made up of a multi-leaf structure. In this case, the structural thickness of the load-bearing wall is much less significant than the geometrical one, thus manifestations of the leafs-separation may easily occur when leafs transversal connections (e.g. diatones) are completely absent or inadequate. In order to avoid this deleterious phenomenon, commercially available connectors are commonly utilized.

The main aim of the research is to investigate the ability of different types of connector of joining a Multi-Leaf Masonry (MLM) and, at the same time, improving the shear bearing capacity of the wall. In this perspective, an experimental campaign was conducted on small-scale MLM-panels, separated by a poor-resistant inner-core. At this scope natural stone diatones, fiberglass ropes, steel-base ropes, L-shaped glass and steel-helix were used to join MLMs. Thus, the shear tests were performed. Finally, an MLM, strengthened by a Glass Fibres-Reinforced Polymer (GFRP) was also tested for a further comparison. It was found that, depending on the type used, the transversal connections effectively improved the strength of the specimen. Lastly, an empirical model was herein proposed and validated.

砌体建筑遗产包括各种各样的砌体类型。通常，表观的厚壁经常由多叶结构组成。在这种情况下，承重壁的结构厚度远不如几何壁厚，因此，当完全没有叶片横向连接（例如透音）时，叶片分离的表现很容易发生。为了避免这种有害现象，通常使用可商购的连接器。

该研究的主要目的是研究不同类型连接器连接多叶砌体（MLM）的能力，同时提高墙体的抗剪承载力。从这个角度出发，对由抗性差的内芯隔开的小尺寸MLM面板进行了实验。在此范围内，使用天然石材的渗色，玻璃纤维绳，钢基绳，L形玻璃和钢螺旋来连接传销。因此，进行了剪切测试。最后，通过玻璃纤维增​​强的聚合物加强了传销（GFRP）也进行了测试以进行进一步的比较。发现根据所使用的类型，横向连接有效地提高了样品的强度。最后，本文提出并验证了经验模型。
