Fatigue Behavior of Large-Scale Reinforced Concrete Beams Strengthened in Flexure with Fiber-Reinforced Polymer Laminates

Life cycle reliability assessment of reinforced concrete beams shear‐strengthened with carbon fiber reinforced polymer strips in accordance with fib bulletin 14

“…However, the high resistance of the FRP, especially carbon fiber reinforced polymer (CFRP) to corrosion, environmental degradation, and fatigue can significantly enhance the lifetime of the strengthened element, even if subjected to harsh environments. This makes them an increasingly prevalent technique in structural strengthening …”

“…Because environmental harshness causes the governing fracture mechanism to be time‐variant, it is necessary to evaluate the strengthening vulnerability using time‐dependent reliability analysis. The current study was undertaken to measure the robustness of RC beams shear‐strengthened with CFRP according to fib bulletin 14 after they have been subjected to different levels of environmental aggressiveness using a reliability‐based life cycle assessment method.…”

“…This makes them an increasingly prevalent technique in structural strengthening. [5][6][7][8][9][10][11][12][13] For the RC beams shear-strengthened with U-shaped CFRP strips, the governing failure mode and its related capacity may be varied based on different design parameters such as interaction between FRP contribution to existing matarials, [14][15][16][17] the predictive accuracy of the proposed design codes/recommendations, 6,18 geometrical and mechanical Discussion on this paper must be submitted within two months of the print publication. The discussion will then be published in print, along with the authors' closure, if any, approximately nine months after the print publication.…”

“…This may be due to the collaboration of concrete and reinforcement which is mechanically difficult to describe as a precise closed-form formulation 25 and additionally when the FRPs are added to the RC beams, the interactions between different load-carrying materials with different strain-stress behaviors will make the problem even more complicated. 26 Because environmental harshness causes the governing fracture mechanism to be time-variant, 6,8,11,27 it is necessary to evaluate the strengthening vulnerability using timedependent reliability analysis. The current study was undertaken to measure the robustness of RC beams shearstrengthened with CFRP according to fib bulletin 14 28 after they have been subjected to different levels of environmental aggressiveness using a reliability-based life cycle assessment method.…”
