The objectives of this proposed research are to perform forced vibration tests on the following reinforced concrete structures, which are permanently instrumented for recording their dynamic responses in the case of future earthquakes in Turkey: a four-story dormitory building in Bolu, a four-story office building in Istanbul, a five-story hospital building in Antakya, a three-story school building in Antakya, and a four-story university building in Izmir, and to derive seismic fragilities for these structures to evaluate their seismic vulnerability. The structural dynamic properties identified from the forced vibration tests will be used in validating or calibrating the-state-of-the-art finite element models of these structures. These structural models will then be used in developing probabilistic seismic risk assessment tools in the form of fragility curves for these permanently instrumented structures. The end-product of this study, the seismic fragilities, will serve the building owners and local authorities in pre-earthquake planning to mitigate probable losses and in post-earthquake planning to develop emergency response and recovery strategies in earthquake prone regions of Turkey.
