Abstract:This paper presents an approach for considering a wide variety of compositematerials in reliability-based design of composite strengthening of concrete structures.The approach is based on the use of the mean value of composite properties as thedesign value and having a composite specific resistance factor that is a function of theCOV of the composite properties. Strengthening design of a simple beam with threemodel composites is used to demonstrate the feasibility of this approach. Forcomparison, designs are created using two existing strengthening guidelines, ACI 440and TR55. These designs are shown to have a high degree of variability in theirreliability and demonstrate the need for a reliability based design procedure. Some ofthe critical areas of further research required for further development of this designprocedure are briefly discussed.
