Evaluation of using Frp Bond Equations in Alternative Types of Advanced Composite Externally Bonded to Concrete

Abstract

The use of advanced composite materials has become common for increasing the structural element capacity. Most of the structural buildings are in need of strengthening to extend their service life as a result of changing their function or by steel reinforcement deterioration in the form of corrosion. The bond performance of fiber reinforced polymer (FRP) in both techniques (NSM or externally bonded) has been extensively studied in the past. As a result, several equations have been derived and proposed to predict both the maximum load and the effective bond length for FRP-concrete joints. On the other hand, there is no standard code or specific proposed model to predict the bond performance of the new generation of advanced composite (steel reinforced polymer or SRP). This paper is an attempt to evaluate the possibility of using FRP bond equations in predicting SRP bond behavior based on wide range of database collected from literature. The reason behind this attempt is that both FRP and SRP systems have the same concept of using organic material as a paste material. As a conclusion, the selected equations used in FRP composite system underestimated in term of SRP behavior prediction.
