ABSTRACT
Prediction of moment capacity of concrete slabs singly reinforced with carbon fiber reinforced plastics (CFRP) using simulated annealing is looked into. Equations for resistance moment are obtained based on the flexural requirements presented in ACI 440. 1R-06 (2006). These equations are then optimized using the Simulated Annealing (SA) algorithm. The developed algorithm is implemented using Visual Basic for Application (VBA). In addition, identification of design variables, objective function and constraints are also presented. The most important factors which influence the ultimate load carrying capacity of CFRP reinforced concrete structures are- effective depth (d) and breadth (b) of the member, concrete strength () and the material properties of the CFRP reinforcement. Thus, the ultimate moment of resistance based on concrete failure obtained for a CFRP singly reinforced concrete section is , this is 22.4% lower than the predicted in the code formulation.
