THANASIS TRIANTAFILLOUΤhanasis Triantafillou received the Diploma in Civil Engineering from theUniversity of Patras (1985), and the M.Sc. (1987) and Ph.D. (1989) Degreesfrom MIT.He is Professor in the Department of Civil Engineering at the University ofPatras, Greece, and Director of the Structural Materials Laboratory.He worked as Assistant Professor in the Department of Civil and EnvironmentalEngineering at MIT and as Visiting Professor in the Swiss Federal Laboratoriesfor Materials Testing and Research (EMPA). He CONFIRMADOjoined the University of Patrasin 1994.He is the author of 5 books, 15 book chapters, 50 papers in international scientific Journals, 100papers in conference proceedings and 80 research reports. He has been scientific coordinator in 27research projects with funding from private or public organisations and the European Commission.Dr. Triantafillou has received several awards, including: (a) 3 best paper awards (2003, 2002, 1997)from the ASCE Journal of Composites for Construction and Journal of Materials in Civil Engineering;(b) the International Institute for FRP in Construction (IIFC) Medal (2010); and (c) the Golden MirkoRoš Medal from the Swiss Federal Laboratories for Materials Testing and Research (EMPA) for life’swork in the field of Materials and Engineering Science (2007). He has extensive consultingexperience in the field of advanced materials and strengthening/seismic retrofitting of structures.Dr. Triantafillou is a member of several International and National Scientific Committees and Societies.He is the convenor of the Working Party EBR (Externally Bonded Reinforcement) of the fib TaskGroup 9.3 and member of the International Editorial Board for the ASCE Journal of Composites forConstruction.His main research interests are focused in the application of advanced structural materials (e.g.polymer composites, textile reinforced concrete, lightweight/fibre-reinforced concretes, highperformanceconcrete) in structures, with emphasis in the field of repair/strengthening and seismicretrofitting.ABSTRACT: INNOVATIVE MATERIALS FOR THE REHABILITATION OF BUILDINGSThe need for upgrading existing structures has been tremendous in the past couple of decades, bothin non-seismic areas due to deterioration and/or the introduction of more stringent designrequirements, and in seismic areas, where structures designed according to old seismic codes have tomeet performance levels required by current seismic design standards.One of the most popular upgrading techniques involves the use of fibre-reinforced polymers (FRPs),which have many favourable properties, namely: extremely high strength-to-weight ratio, corrosionresistance, ease and speed of application, and minimal change in the geometry.Despite all these advantages, the FRP strengthening technique has a few drawbacks, which areattributed to the organic resins used to bind or impregnate the fibres.An interesting solution to problems associated with resins is their replacement with inorganic mortars,resulting also in the replacement of continuous fibres with textiles.The resulting advanced composite materials, known as Textile-Reinforced Mortars (TRM), form thebasis of state-of-the-art techniques for the rehabilitation of structures.During the past 7 years or so, the author has conducted intensive research in the use of TRM asstrengthening and seismic retrofitting materials of reinforced concrete and masonry structures.These materials have been used successfully in flexural strengthening of beams and two-way slabs,in shear strengthening of beams, in confinement of columns, as well as in out-of-plane and in-planestrengthening of masonry.Experimental and analytical results indicate that the new strengthening technique is extremelyeffective and promising in the area of structural rehabilitation.The main outcome of studies in this field will be given during the presentation.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 25
