Local red brick masonry structure is widely used as the main structure housing. In any event a large earthquake in Indonesia, the collapse of the masonry structure is always there. Theories that explain the masonry structure in Indonesia refer to the references from other countries. This is due to research published in Indonesia is not a lot. The theory that widely used in the equations for masonry structures based on the strength of brick units higher than the mortar. Preliminary results and review of literature shows the strength of local brick unit in Indonesia is lower than the strength of mortar. The same thing happened also with its physical properties. The aim of this study is to obtain a more appropriate theoretical for the behavior of local masonry structures, especially the material from East Java. The independent variables in this study are the thickness of mortar and the strength of mortar. Mortar strength obtained from a mixture that is often used in Indonesia. The results showed the thickness and the strength of the mortar has positive influence on the strength of masonry structures. This behavior is different from the existing theoretical studies in foreign literature. The ductility of masonry wall is obtained higher in the mortar with a lower strength.
