Résumé en anglais
Governmental regulations are inadequate to deal with the strengthening of historic buildings as these are prepared for new construction. Historic buildings have often survived several earthquakes which come at intervals of between 50 and 100 in many regions. This paper aims at making architects without specialised knowledge of engineering avare of the problems of historic buildings in earthquake zones. The typical sequence of collapse is examined and methods of strenghthening historic buildings are reviewed.
