“…Diagonal shear stress testing is done by making a square test object measuring 40-120cm (Mahlil, Abdullah, 2014;Tsantilis & Triantafillou, 2018;Ullah et al, 2022), then applying pressure in the diagonal direction. When setting up the test object, do it carefully and carefully.…”

The strength of a brick wall is influenced by the failure of the mortar bond and the resistance of the bad joint and head joint when carrying the force. The wider the head joint and bad joint areas result in a wider bonded area which increases the diagonal shear strength of the wall. Residential walls that have increased ability to withstand diagonal shear forces will be more stable when subjected to earthquake lateral forces. This research formulates that the wider the connecting area of the body and head joint, the higher the diagonal shear strength. The test was carried out by making a square test object measuring 60 x 60 cm. then pressure is applied in the diagonal direction. At the time of setting up the test object is done carefully and thoroughly. The test object is positioned perpendicular to the diagonal direction. The test object is placed absolutely perpendicular and is given a load until it is completely damaged. Loading method by providing a force that increases regularly until the structure experiences a complete failure. The bonded area in each brick shape is measured and compared with the results of the diagonal shear strength. This value is analyzed to obtain the effect on the diagonal shear strength. The percentage effect of each brick shape is compared and the results are analyzed. The results of the analysis are to obtain justification whether the area of the bad joint and head joint affects the diagonal shear strength. The novelty of this research is to obtain several brick designs that increase the strength of the diagonal shear stress. Tests show that the greater the area of the head joint, the greater the value of the diagonal shear stress.

“…The critical parameters, such as shear stress, strain, failure modes, ductility, energy dissipation, and stiffness degradation, were investigated. Compared to reference and plastic-reinforced specimens, the steel-reinforced brick samples with cement mortar were found to be highly effective [12].…”

“…Horizontal load -displacement graphics for unreinforced wallsThe single-sided reinforced wall specimens exhibited similar fracture behavior. It was observed that a diagonal fracture occurred on the non-reinforced surface, while grid cracks formed on the mesh reinforcement lines of the reinforced surface(Figures 11,12,and 13). Horizontal load-displacement graphics for one-sided reinforced walls are presented in Figure14.…”

The strengthening of masonry structures is of paramount importance due to their inherent lack of tensile elements, rendering them susceptible to tensile stresses induced by horizontal loads and the resultant substantial damage. Consequently, this study aims to develop a reinforcement system for the strengthening of historical masonry structures by using mortars devoid of cement and modern pozzolan. Experiments were conducted on masonry walls unreinforced and reinforced by a one-sided Khorasan mortar with steel mesh. Initially, six masonry brick walls constructed using Khorasan lime mortar were prepared. Subsequently, after a waiting period of six months, Khorasan plaster mortar, reinforced with steel mesh, was applied to three masonry walls on one side. Following an 18-month waiting period, all samples were subjected to testing in an experimental setup designed and manufactured for this purpose. The wall reinforcement resulted in a significant increase, with the average peak load by 215.73%, and the average displacement by 48.82%. The experimental shear force on unreinforced walls was found to be 41.23% lower than Eurocode-6 and 1.41% lower than TBDY-2018. In the case of one-sided reinforced walls, the experimental shear force was 9.94% lower than Eurocode-6 and 6.16% lower than TBDY-2018. This form of strengthening not only obviates the use of potentially damaging cement in historical buildings but also extends the lifespan of the reinforced structures.
