The Value of the Diagonal Shear Stress of the Masonry on Laboratory Testing

The earthquake resulted in structural, non-structural damage, material and non-material losses and even death. Material losses in the form of damage to houses, household furniture, loss of property. Non-material losses in the form of loss of peace, comfort. The above damage is anticipated by increasing the brick wall elements which contribute well to increasing its capacity to carry the combined external forces that occur during the earthquake. In particular, increasing the strength of a brick wall can be done by selecting the quality of the wall constituent materials and designing the brick wall. This research is addressed to investigate the value of the diagonal shear stress of the masonry brick due to the external forces. The testing was carried out as laboratory testing by using the preference model and method. The results of this study is that normal bricks reach 1500 to 1800 Kgf, and the normal diagonal shear stress reaches 1.6603788 Kg/cm2, while initial cracking at 400 to 800 Kgf, later cracking at 800 to 1,000 Kgf and failing at 1,500 – 1,800 Kgf
