Abstract

Indonesian local brick in the masonry wall with a cement-based mortar has different physical and mechanical characteristics from the developed countries that are always used as references. Because of the different behavior with another countries and low strength of local brick, it requires a lot of research to get the strength reduction factor (R) and the displacement amplification factor (Cd). It is important in order that the design of earthquake resistant buildings in Indonesia more rational with the use of local brick. The study was conducted using cyclic loading with the appropriate protocol to simulate earthquake loads on the model structure that has been scaled. To increase the low performance of confined masonry wall, bamboo strips were used as reinforcement for some models. The study discussed the value of R and Cd towards the Indonesian and developed countries code. The results showed the mechanical characteristics of local brick masonry with cement-based mortar is different from developed countries. The basic differences are the strength and stiffness of the local brick lower than mortar as a binder. This results showed that utilizing equations R and Cd from developed countries needed further attention for local brick masonry in Indonesia.
