Abstract

This paper presents the seismic performance of RC columns retrofitted with steel plates and FRP sheet. The test columns were subjected to cyclic lateral loads under lateral displacement control. The column section was 300 mm×400 m, and the shear span was 1200 mm. The test columns were designed to replicate existing columns, of which the ratio of the shear strength to the flexural strength was 0.69.The failure mode of the column without retrofitting was not the shear failure, but the bond slippage failure. The maximum shear strength of the retrofitted columns had the 1.4~1.5 times that of the column without retrofitting. The increased strength of the retrofitted column could be estimated by accumulating the strength of the added column to that of the original column.
