Modeling of Near-Surface-Mounted Carbon Fiber- Reinforced Polymer for Strengthening Reinforced Concrete Beams in Sustained Load
This article presents a theoretical model for predicting the long-term behavior of near-surface-mounted (NSM) carbon fiberreinforced polymer (CFRP) strips embedded in a reinforced concrete beam subjected to creep-induced distress. The concept of age-adjusted effective properties is employed, including timedependent material characteristics. Upon validation of the modeling approach using a previously conducted test program, a parametric investigation is performed to examine the effect of various material parameters such as concrete strength, CFRP modulus, and reinforcement ratio. A design proposal is made to facilitate NSM CFRP technologies for practical strengthening application. Four design categories are suggested depending on the level of sustained load. The proposed long-term design factors are in conformance with the time-dependent multipliers of ACI 318-11.
