摘要：

This paper reviews the performance of shear strengthened reinforced concrete (RC) beams with the use of externally bonded mortar-based composite jackets (e.g. FRCM, ECC, UHPFRC). An experimental database was compiled gathering all the known studies in strengthening shear deficient RC beams using innovative mortar based systems. The role of the RC beams' inherent deficiencies as well as the impact of the design parameters of the alternative jacketing configurations were identified. Existing design models proposed to predict the contribution of the mortar-based composites to the shear strength of RC beams were assessed using the database and conclusions were drawn regarding their accuracy.
