To investigate the influence of CFRP and fine aggregate type on strengthened seismic performance of corroded reinforced concrete short columns(RCSCs), the pseudo-static tests of one un-corroded reinforced concrete short column reinforceel concrete short column(RCSC), two corroded RCSCs and four corroded RCSCs strengthened with CFRP were carried out in this study. Besides, a practical method to calculate the shear strength of corroded reinforced concrete columns strengthened with CFRP was suggested. Experimental results show that the corrosion of steel bars will weaken the seismic performance of short columns. The shear bearing capacity, ultimate deformation capacity and cumulative hysteretic energy dissipation of corroded RCSCs are reduced by 7.8%, 35.5% and 42.2%, respectively. CFRP wrapping can enhance the shear strength of corroded RCSCs to a level of 107.1%~109.1% of that un-corroded RCSC, and can significantly improve the ductility and energy dissipation capacity of corroded RCSCs. When CFRP layer is increased from one to two, the shear capacity of the reinforced specimen is marginally improved, and the maximum strain of CFRP decreases when the specimen reaches the peak load. Moreover, the hysteretic rules for the dimensionless hysteresis loops of RCSCs closed to limit state for cases with un-corrosion and with corrosion, without CFRP strengthening and with CFRP strengthening are similar.
