PSEUDO-DYNAMIC TESTS ON REPAIRED AND RETROFITTED BRIDGE COLUMNS

摘要：

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 wrapping. Pier specimens are representative of tall and squat circular r.c. piers designed according to Eurocode 8 and Italian Code before 1986. The study comprehends preliminary tests carried out on self compacting concrete and stainless steel bars, as well as pseudodynamic tests in order to evaluate the effectiveness of adopted repairing and upgrading techniques to increase both ductility and shear strength.
