ABSTRACT: This research aims to study the seismic performance of existing r.c. bridge piers specimens heavily damaged after previous pseudodynamic tests and actually repaired and upgraded by using self compacting concrete, stainless steel rebars and CFRP wrapped strips. Pier specimens are representative of tall and squat circular r.c. piers designed according to Eurocode 8 and Italian Code before 1986: EC8 columns are repaired and Italian ones retrofitted to enhance ductility and shear capacity. Innovative materials have been used and such interventions are described in details with particular attention to practical problems occurred. Experimental test results carried out at the Laboratory of experiments on materials and structures of the University of RomaTre on self compacting concrete and stainless steel bars are shown and discussed. Retrofitting design and equipment for pseudodynamic tests are also presented. In coming tests aim to evaluate the effectiveness of adopted repairing and upgrading techniques not only to increase ductility but shear strength too.
