Abstract

In order to ensure safety of deteriorated reinforced concrete (RC) structures, an effective rehabilitation plan is essential. Although considerable research on strengthening of RC structures using Fiber Reinforced Polymers (FRP) composites has been undertaken, prediction of optimum strengthening time has not adequately been studied. This paper presents a methodology for optimal strengthening of corrosion-affected RC columns. An optimization problem based on minimization of total cost is formulated, from which optimum strengthening time and number of required FRP layers can be obtained. The results from a worked example show that an optimum solution to the formulated strengthening problem exi..
