Enhancing Resilience and Self-Centering of Existing RC Coupled and Single Shear Walls Using EB-FRP: State-of-the-Art Review and Research Needs

The primary seismic force-resisting system (SFRS) in middle- to high-rise reinforced concrete (RC) building structures often includes coupled shear walls (CSWs) and single (SSWs). These are designed transfer lateral forces the foundation dissipate energy through development of plastic hinges. latter lead residual displacement these structural components. On other hand, self-centering systems enable return their initial position after severe loading or at least reduce displacement. objectives this study were, therefore, as follows: (i) review state art on wall techniques retrofitting methods based externally bonded fiber-reinforced polymer (EB-FRP); (ii) evaluate research needs improve ability using EB-FRP.
