A challenge of retrofitting a historical building

Buildings with historical value are regional cultural assets worth preserving. At times, they also represent a potential source of revenue and stimulus for the economical revitalization of their neighborhoods. The building preservation and restoration is an multidisciplinary activity which makes it difficult to establish rules and codes, and this leaves the designers tapping in the dark. Lack of clear guidelines can easily lead to ambiguities and weakly funded decisions based on past experiences that may also be phallic. Recently, earth has on numerous occasions shown its power of nature and natural forces by earthquakes. Replacing the existing buildings with “earthquake-resistant houses” is neither feasible nor desirable. Giving the building occupants a fair chance of escape in the once-in-a-lifetime event of a large earthquake should be in everyone’s interest. Seismic retrofitting of buildings is still a new activity for most structural engineers, and in many countries still a quite neglected topic. This article is presenting the structural renovation theory for historical buildings. The needed approach to the challenge of retrofitting a historical building is shown. Due to length restrictions the theory is supported by a historical building example strengthened keeping reversibility of retrofitting in mind with only several examples.
