TL;DR: In this article, the durability of the adhesive bond between concrete and carbon fiber reinforced polymers (CFRP) strengthening systems has been investigated under accelerated ageing conditions, i.e., at 40°C and 95% relative humidity.

TL;DR: In this article, a truly distributed sensing system was used to monitor the mechanical behavior of a representative-scale reinforced concrete structural element tested in four-point bending, which was found to be consistent with both experimental data obtained from conventional vibrating wire gauges and theoretically predicted strain profiles, and showed no influence of the sensor location on quantitative results (externally bonded sensors, cables embedded near/far from the rebars).

TL;DR: In this article, the experimental determination of the bond behavior between ultra-high performance fiber-reinforced concrete (UHPFRC) and reinforcing bars (rebars) was carried out to assess the bond behaviour considering different rebar diameters, different embedment lengths and different concrete covers.

TL;DR: In this paper, two complementary techniques, shearography and pulsed stimulated infrared thermography, are used to detect and characterize depth and width of the adhesion defects (delaminations or adhesive disbonds) of externally bonded fiber-reinforced polymers (FRP) on concrete surface structures.

TL;DR: In this article, an iterative computational method based on section equilibrium and material properties (concrete, steel, adhesive and composite) has been developed: this method can be extended to describe the fatigue behavior of RC beams.
