There is an urgent need to retrofit the deficient mid-rise reinforced concrete frame buildings in Turkey. For this purpose, an efficient FRP retrofit scheme was developed, in which hallow clay brick infill walls are utilized as lateral load resisting elements. The main premise of this practical retrofit scheme is to limit interstory deformations by FRP strengthened infill walls that are integrated to the boundary frame members through FRP anchors. Based on failure modes and measured deformation limits obtained from a large database of experiments, a diagonal compression-strut and tension-tie model is developed. The model is verified with a number of reinforced concrete frame test results with and without upgrades. Furthermore, results of a case study conducted on a typical building frame revealed that strength levels similar to that of a RC shear wall retrofit scheme can be obtained through the FRP retrofit alternative resulting in a displacement ductility of about four.
