In a time when sustainability and efficient resource management are paramount, innovative application of existing and novel materials is essential. Although carbon fiber-reinforced polymers (CFRPs) have been utilized successfully in the building and infrastructure sectors for decades, their full potential seems unrealized as efficient activated structural strengthening solutions. This research paper investigates an un-bonded ductile CFRP strengthening system used in a multi-system configuration. With a background in ongoing and previous studies which demonstrate a controlled ductile response when bonded and semi-bonded to reinforced concrete (RC) structures, this study aims to evaluate the test response, capacity, and reliability benefits of the multi-system configuration. A representative comparison of two RC slab specimens (245 × 1085 × 2875 mm) will be shown: One specimen serving as a reference, and the other strengthened with the un-bonded and externally applied ductile activated CFRP system. The results indicate that the system substantially strengthens while maintaining ductility and enabling response control. It is further hypothesized that the demonstrated and well-controlled ductile response of the multi-system configuration could allow for significantly enhanced safety. The system is shown to provide a substantial strengthening effect until structural failure occurs. Still, the system will stay undamaged, thus allowing for system de-mounting or replacement after structural damage. The unique response, fast mounting procedure, high capacity, and lightweight unbonded strengthening system highlights CFRP benefits, and consequently makes it attractive to building and infrastructure managers as an efficient strengthening solution.
