Abstract:

In recent years seismic isolation technologies in Armenia were extensively applied in construction of multi-story residential and business center complexes with parking floors and with floors envisaged for offices, shopping centers, fitness clubs, etc. They are briefly described in the paper, which is, however, mainly dedicated to a 17-story base isolated apartment building “Sevak” designed and constructed recently in the city of Yerevan. The structural concept, including the new approach on installation of seismic isolation rubber bearings in this building, is described and some results of the earthquake response analyses are given. The building was analyzed using several time histories and also according to the requirements of the Armenian Seismic Code. Comparison of the obtained results indicates the high effectiveness of the proposed structural concept of isolation system and the need for further improvement of Seismic Code provisions regarding the values of the reduction factors.
