This study presently in progress, aims to assess the seismic performance of circular r.c. bridge piers specimens heavily damaged after previous pseudodynamic tests and repaired and/or upgraded by means of epoxy adhesive, stainless steel rebars, self compacting concrete and CFRP wrapping. Pier specimens are representative of tall and squat circular r.c. piers designed according to Eurocode 8 and Italian Code before 1986. Preliminary tests were performed on stainless steel bars and self compacting concrete. Pseudodynamic tests are now in progress, in order to evaluate the seismic response of repaired and upgraded piers with the aim to increasing both ductility and shear strength.

Abstract
This study presently in progress, aims to assess the seismic performance of circular r.c. bridge piers specimens heavily damaged after previous pseudodynamic tests and repaired and/or upgraded by means of epoxy adhesive, stainless steel rebars, self compacting concrete and CFRP wrapping. Pier specimens are representative of tall and squat circular r.c. piers designed according to Eurocode 8 and Italian Code before 1986. Preliminary tests were performed on stainless steel bars and self compacting concrete. Pseudodynamic tests are now in progress, in order to evaluate the seismic response of repaired and upgraded piers with the aim to increasing both ductility and shear strength.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
