| Abstract: |
This research focuses on the effects of base isolation on annual probable seismic loss in a typical existing educational building. The physical seismic damage is related to economic losses to investigate the financial aspects of application of base isolation system in building. Meanwhile the probabilistic nature of both seismic event and structural response has been considered by the employed methodology. The building, which experienced the 2012 East Azerbaijan –North West of Iran- twin earthquakes, suffered non-structural damage. The annual probable seismic loss is evaluated for both structures. The existing information of the seismic hazard of area and fragility curves of buildings were employed from previous research. The results indicate that although the initial cost of the project may increase due to application of base isolation, the overall probable loss is reduced due to lower vulnerability of the building equipped by such equipment. |
