The strengthening of reinforced concrete structures with steel plate bonding techniques are currently being replaced by fiber reinforced polymer (FRP) laminates. Carbon Fiber Reinforced Polymer (CFRP) is a quite new material and the rheological behavior of structural materials is significant. The studies focusing on long-term behavior of FRP-strengthened concrete elements. The aim of this paper was to compare two strengthening methods: near surface mounted reinforcement (NSM CFRP) and CFRP strip bonding technique. It presents results of experiment performed on three bonding concrete beams with dimensions of 150 x 250 x 3300 mm, under sustained load.
