EVALUATION THE SHEAR STRENGTH OF FIBROUS REACTIVE POWDER CONCRETE BEAMS STRENGTHENED WITH CFRP STRIPS
A new expression for estimating the ultimate shear strength of steel fibers reinforced high strength concrete (SFRHSC) beams strengthened with CFRP strips based on previous researches is proposed in this research. The proposed expression covers different characteristics and principal parameters such as concrete compressive strength, shear span to effective depth ratio, volume fraction of steel fibers, CFRP amount and distribution, CFRP stiffness, deep beam effect, as well as the end anchorage state of the CFRP strips with the beam. A comparison between computed values and experimentally observed values (with a low COV of about 3.58 %) shows the validation of the proposed theoretical treatment.
