Abstract

The primary concerns in rehabilitation of existing structures are strength and ductility of the system but sometimes the deformation of a member may become critical. The flexural behavior of a RC beam strengthened with externally bonded reinforcement (EBR) such as Fiber Reinforced Polymer (FRP) sheets is well understood but the deflection of the member is a topic that not many researchers have addressed over these years. Design guidelines have pointed out to some simple and approximate ways to calculate the deflection but a more accurate relationship is needed to prevent unexpected behavior under service and ultimate loads. In this study, an effort was made to find a suitable relationship for estimating the deflection of RC beams strengthened with FRP laminates using EBR technique. Prediction of the deflection is made at service load level by determining different values for effective moment of inertia. Results of several experimental works done by other researchers were used to validate the accuracy of the proposed equations. The experimental results correlated well with the values predicted using the proposed simple equations with less than 17% error.
