Title
(EN) SEISMIC PERFORMANCE IMPROVEMENT OF FRP-RC STRUCTURES
(FR) AMÉLIORATION DE PERFORMANCE SISMIQUE DE STRUCTURES PRF-BA
Abstract
(EN)
Although Fiber Reinforced Polymers (FRPs), as alternatives for the corrosive steel reinforcement in concrete structures, have shown promising performance under gravity loads, their performance under reversal cyclic loading is still one of the main concerns. The linear behavior of FRP reinforcement has a two-sided effect on the seismic performance of FRP-reinforced concrete (RC) moment-resisting frames. Although the linear nature of FRP reinforcement could be advantageous in terms of limiting the residual damage after an earthquake event, it lowers the energy dissipation of the structure which can compromise its seismic performance. Disclosed herein is the addition of steel plates at selected locations in moment-resisting frames to improve seismic performance of FRP-RC structures while still being able to take advantage of its linear behaviour (minimal residual damage after earthquake). The effectiveness of the proposed solution was tested both experimentally and analytically.

Bien que des polymères renforcés de fibres (PRF), en tant qu'alternatives pour le renforcement d'acier corrosif dans des structures en béton, aient montré une performance prometteuse sous des charges de gravité, leur performance sous une charge cyclique inversée est encore l'une des préoccupations principales. Le comportement linéaire de renfort PRF a un double effet sur la performance sismique de cadres rigides en béton armé (BA) PRF. Bien que la nature linéaire de renfort PRF pourrait être avantageuse en termes de limitation des dommages résiduels après un événement de tremblement de terre, elle diminue la dissipation d'énergie de la structure qui peut compromettre sa performance sismique. L'invention concerne l'ajout de plaques d'acier à des emplacements sélectionnés dans des cadres rigides pour améliorer la performance sismique de structures PRF-BA tout en pouvant encore tirer avantage de leur comportement linéaire (dommages résiduels minimaux après tremblement de terre). L'efficacité de la solution proposée a été testée, à la fois expérimentalement et analytiquement.
