The experimental campaign was carried out regarding the evaluation of: i) shear retrofit strategy efficiency and ii) the influence of different transverse reinforcement details on the shear capacity and concrete confinement. The experimental campaign has been carried out at LESE – FEUP (Laboratory of Earthquake and Structural Engineering of the Faculty of Engineering of University of Porto), on a set of four RC piers with hollow section. Within the scope of this work it is also the study of design procedures for CFRP shear retrofitting and the evaluation of the associated ductility capacity improvement. Efficiency assessment is pursued for different scenarios of shear failure prevention, and the corresponding seismic response enhancement is evaluated. The most relevant experimental information is presented in the paper, as for instance the evolution of shear cracks and the illustration of the outside and inside damage pattern.
