The most damage properties when an earthquake happens in Indonesia is occurred in the simple building with infilled brick wall. It was caused the building is classified as a non engineering building. In SNI, the determination of the brick wall as non structural component are causing the strength and stiffness of the bric wall are never calculated in the building design process. In fact, the strength and stiffness of the brick wall ae significantly affected the behavior of the simple house building.
In this study, there are three panel model of reinforced concrete structure with 4 m,
3 m and 2 m in width, with both of them are one story building, and functioned as residential, located in the high risk Indonesian seismic zone (zone 6), and designed using force based structural design. After the beam and column properties are obtained, then it is analyzed. Simultaneously with the brick wall with different arrangement and boundaries. the thickness of the brick wall was assumed as one and half brick arrangement with three and four faces boundary. moreover, in the structural analysis the brick wall are modeled as compression bracing. therefore, there are 12 different structural model that being analyzed.
The result of this study shows that the structural system with infilled brick wall has better ductility value and higher base share capacity compared to the open frame structural system. Additionally, the performance evaluation present the structural system with infilled brick wall are able to achieve the Life Safety – Collapse Prevention range instead of open frame structural system which is only achieve the Immediate Occupancy category. |
