Abstract

Earthquakes are disasters that cause vibrations and can cause damage to infrastructures. Thus, there is an urgent need to provide safe buildings against severe earthquakes to avoid any structural failures. One of the most effective systems for buildings against earthquakes is the seismic isolation system. The study aims to analyze and evaluate the efficient configuration of the isolation system to the structural responses of the buildings against earthquakes. The method used was to introduce the isolation system between story levels by placing them on the floors. The most efficient results in terms of structural responses were when the isolations were placed at the 1st and 5th stories, e.g., building periods, inter-story displacements, story shear, and internal forces. Placement of isolations with better response was obtained for isolations located at two stories than only a story. This implied that it served more effectively and better in minimizing structural damage. The isolations were ineffective when they were located on the 7th story, the results indicated that the inter-story displacement and story shear were insignificantly affected. From the analytical results due to the earthquake load, it was also found that the isolations on the 1st and 5th stories experienced the most significant responses, whereas the placement on the 7th story had an insignificant impact in minimizing structural damage due to earthquake load.
