This paper presents a numerical investigation on the behaviour of prestressed concrete (PC) girders strengthened in shear with externally bonded carbon fiber reinforced polymer (CFRP) strips. A three-dimensional finite element model was developed and validated against published experimental results. The FE model was then used to carry out a parametric study to investigate the effect of concrete compressive strength and CFRP reinforcement ratio on the shear force capacity of PC girders. An increase of 48% in the shear force capacity was predicted when the concrete strength was increased from 25 MPa to 59 MPa. The increase in the CFRP reinforcement ratio from 0 to 2.45% resulted in 25% increase in the shear force capacity.
