SenthivelResearch, Development and Innovation DepartmentAcciona Infrastructures, Madrid, Spain.Key words: masonry infill, soft story, silt column, seismic analysis, dynamics, earthquakeAbstractA large number of existing historical cultural heritage buildings in the world needsretrofitting. The April 6, 2009 morning L'Aquila (a historic city found in 13th century)earthquake in Italy caused significant damage to historical buildings. In general, most of thehistorical buildings are non-standard and do not meet the current level of desired structuralsafety. The authors have visited the different historical building sites located in and aroundMadrid region including Toledo, Segovia, Cuéllar, Samboal, Coca and Arévalo. The historicalholy city, Toledo is located in the South of Madrid and the other cities are locatedapproximately in the North of Madrid (Spain). From the on site visual inspection, observationand data collection, the historical buildings are classified into three types depends up on theconstruction materials used. An effective unobtrusive retrofitting technique using head andbed joint FRP (Fibre Reinforced Polymer) rebar reinforcement is proposed for upgradingstrength of the historical buildings to meet the current structural safety code requirements.The retrofitting materials (such as primer, epoxy, and FRP rebars) in the proposed retrofittingtechnique is designed, developed and manufactured at the Acciona Infrastructures and testedat the laboratory. This paper presents outline of the historical building site visit and propose aFRP (GFRP) retrofitting techniques for historical buildings.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 290
