Full-Scale PsD Testing of the Torsionally Unbalanced SPEAR Structure in the 'As-Built' and Retrofitted Configurations

In the framework of the research activity of the ELSA Laboratory of the Joint Research Centre, pseudo-dynamic testing of a real-size plan-wise irregular 3-storey frame structure was carried out as the core of the research project SPEAR (Seismic PErformance Assessment and Rehabilitation of existing buildings). The main goal of the SPEAR project was contributing to the improvement of current design, assessment and retrofitting techniques and the development of new simplified approaches for the assessment and rehabilitation of existing building structures, by means of a balanced combination of experimental and numerical activities. The experimental activity carried out at the ELSA Laboratory on the full-size SPEAR specimen consisted of three rounds of PsD tests on the structure in three different configurations: at first, the ‘as-built’ structure was tested; after that, it was retrofitted by means of Fiber Reinforced Polymer (FRP) wraps and then tested again; finally, it was reinforced by means of conventional Reinforced Concrete (RC) jacketing and re-tested to failure. In the paper, the test set-up is presented and the most significant outcomes of the tests are discussed with reference to the open issues of research in the field of torsionally unbalanced buildings.
