Abstract
Earthquake has been one of many disaster issues in Indonesia since many victims were affected. A lot of buildings, especially mid rise buildings type collapsed at the earthquake events because many of its designs were not considering big force that happened. In Indonesia, National Center for Earthquake Studies has published new seismic hazard map in 2017, however few studies have checked the building with the new hazard map. This research performed linear analysis of structural buildings. Reinforced concrete building with the same floor plan and typical structural dimensions was modeled as object of the research, assuming that the mid rise building type in Indonesia is similar with the model. The earthquake loads given to the model were three different time histories which were matched by response spectrum retrieved from hazard map for 99 big cities in Indonesia. Displacements for each floor were compared to the limit stated in Building Earthquake Code 2012, which is 2 percent of its height. The study shows that displacement of same buildings located in some cities are exceed the limit. For further research, the improvement of buildings with additional affordable structural members can be developed.
