Assessment Of The Earthquake Behavior OfHotel Ermionio In Kozani, Greece ConstructedIn 1933 Before And After Its Recent Retrofit

The earthquake behavior of a retrofitted four-story reinforced concrete (R/C) building, which was constructed in 1933 and belongs to the “Nouveau Monuments of Greece”, is investigated here. The predicted earthquake behavior of the old structure, under the provisions of the current Greek Seismic Code, revealed the low resistance of this building to the design seismic loads. The estimate of the strength of existing structural members was based on tests performed in-situ as well as at Aristotle University. The retrofitting scheme included a partial change of the structural system by cast-in-place R/C walls together with the strengthening of all columns and beams by R/C jackets as well as by the use of carbon fiber reinforced laminates (CFRP) for the improvement of the bearing capacity of the slabs. At the same time, all the architectural features of this building were preserved. The predicted earthquake behavior of the retrofitted structure demonstrated its sufficient earthquake resistance.
