Abstract: The SPEAR (Seismic PErformance Assessment and Rehabilitation) research Project, currently being carried out by a consortium of European Partners, is specifically targeted at existing under-designed structures: evaluation of current assessment and rehabilitation methods, development of new assessment and retrofitting techniques, contribution to the improvement of current codes are some of its main goals. In the framework of SPEAR, the core of the experimental activity is the series of full-scale pseudo-dynamic tests on a torsionally unbalanced three-storey RC frame structure, recently carried out at the ELSA Laboratory of the Joint Research Centre. As one of the main goals of the project is to pursue a better understanding of the potential of seismic rehabilitation methods, among which FRP materials certainly represent one of the most promising techniques, the experimental activity of the SPEAR project has foreseen pseudo-dynamic tests both on the ‘as-built’ and the FRP-retrofitted full-scale structure. In the paper, the strategy of the retrofitting intervention, consisting in the application of glass fiber wrapping, is described and the performance of the specimen in the two different configurations during the PsD tests is described. Through the experimental data, the effectiveness of the retrofitting strategy is thus assessed.
