Abstract

It is too important to know the influence of effective parameters on the fractural behavior and strengthening of cracked concrete beams, so the present study is dedicated to numerical analysis of carbon fiber reinforced polymer (CFRP) sheet-strengthened Notched Concrete Beams. The bearing capacity, CFRP Debonding and crack mouth opening displacement (CMOD) of notched beams were evaluated with nonlinear finite element method. Numerical results have been compared with experimental results of other researches. After validation the numerical modeling of CFRP plated notched cbeams, parametric studies reveal quantitatively the effects of various factors such as; thickness of CFRP sheet, compressive strength of concrete, initial crack length and interfacial bond strength on the CMOD curve of mentioned beam, which is found to be characterized by two peak loads. The first and second peak loads increase with the increase in concrete strength, the thickness of CFRP sheet and the interfacial bond strength. It is also found that increasing the initial crack length decreases the first peak load but no exerts on the second peak load.
