Abstract

The study proposes a theoretical model for determining the shear capacity of 2-span continuous reinforced concrete (RC) T-beams strengthened or repaired by Carbon Fiber Reinforced Polymer (CFRP) sheets located at intervals along its span. In an attempt to develop the model, Khalifa and Nanni’s theory on shear capacity was selected. The modification to the theory focuses on the coefficient reduction factor R of the method. The modified coefficient reduction factor was re-applied to Khalifa and Nanni’s model, and a comparison was made from previous experimental work for validation. Results showed a remarkable change when a difference of only 2% to 11 % was observed. This result justifies the applicability of the modified Khalifa and Nanni’s theoretical model in determining the shear capacity of a 2-span continuous reinforced concrete T-beam.
