Abstract:
The SPEAR (Seismic PErformance Assessment and Rehabilitation) researchProject is specifically targeted at existing under-designed structures and, in itsframework, the core of the experimental activity is the series of full-scale pseudo-dynamic tests on a torsionally unbalanced three-storey RC structure, carried out at theELSA Laboratory of the Joint Research Centre. As one of the main goals of the project isto pursue a better understanding of the potential of seismic rehabilitation methods, theexperimental activity of the SPEAR project has foreseen pseudo-dynamic tests both onthe ‘as-built’ and the FRP-retrofitted full-scale structure. In the paper, the strategy ofthe retrofitting intervention, consisting in the application of glass fiber wrapping, isdescribed and the performance of the specimen in the two different configurationsduring the PsD tests is described. Through the experimental data, the effectiveness ofthe retrofitting strategy is thus assessed.
