Abstract

To investigate the seismic performance of rectangular reinforced concrete (RC) columns strengthened with carbon fiber reinforced polymer (CFRP), four full-scale rectangular RC columns were tested under combined constant axial load and unidirectional lateral horizontal cyclic load. The constant axial compression ratio for all the columns was 0.4, while the lateral cyclic displacement was applied in strong axis (i.e. 0 degree) and weak axis (i.e. 90 degree) of specimens, respectively. All the specimens have the identical section of 300 mm × 450 mm and cantilever height of 1400 mm. The failure modes, lateral load-displacement responses, ductility were compared and investigated. The test results indicated that the seismic performance of rectangular RC columns could be significantly improved after being strengthened with CFRP, especially in the strong axis direction. The failure mode of control specimen in strong axis was a more brittle shear model, while the strengthened columns exhibited a more ductile flexural mode. The ductility factor of rectangular RC columns was significantly improved in both strong and weak axis directions after being strengthened with CFRP.
