dc.description.abstractThe present work intends to contribute for the knowledge on durability performance of the near-surface mounted (NSM) strengthening technique, which is an issue that still requires significant research effort. For that purpose, an experimental program was developed using cubic pullout and slab specimens strengthened with NSM carbon fiber reinforced polymer (CFRP) strips. These specimens were submitted to thermal cycles in order to study the effect of this environmental action on the effectiveness of the NSM technique. The thermal cycles were defined according to the EN 13687-3 standard. After being submitted to this action during up to eight months, the specimens were monotonically tested up to failure using four-point bending and pullout direct test configurations for slabs and cubic specimens, respectively. To compare the performance of these specimens with non-aging ones, control specimens were also tested. The obtained results indicate that the loading capacity of the slabs and damage mechanism were not affected by thermal cycles. Nevertheless, the bond strength increased with the number of thermal cycles. Therefore, these results suggest that the concrete elements strengthened with CFRP NSM technique are not susceptible to temperature in a range of -15°C to 60°C.por
