Abstract
Three remarkable projects on retrofitting by base isolation of the existing buildings are described in the chapter. One of them is retrofitting of a 5-story stone apartment building in Armenia. The operation was made without resettlement of the occupants. World practice provides no similar precedent in retrofitting of apartment buildings. The other project is retrofitting of the 60 years old 3-story stone school building also in Armenia. This building has historical and architectural value. Unique operations which were carried out in order to install the isolation system within the basement of this building and to preserve its architectural appearance are described. The third project is development of the design on retrofitting by base isolation of the 180 years old historical building of the Iasi City Hall in Romania. The structural concept of retrofitting is described and detailed results of the earthquake response analysis for two cases, i.e. when the building is base isolated and when it has a fixed base, are given. For all three buildings comparative analyses of the cost of innovative base isolation retrofitting technology vs. the costs of the different methods of conventional retrofitting are carried out and presented.
