Seismic Collapse Risk Assessment and FRP Retrofitting of RC Coupled C-Shaped Core Walls Using the FEMA P695 Methodology

Despite the frequent use of C-shaped reinforced concrete (RC) cores as the primary force-resisting system in multistory buildings, there are still challenges in estimating their inelastic seismic response, especially when they are used as a coupled wall system. Recent studies showed the inadequacy of old code provisions in predicting the seismic shear demands of these systems. This means that many…
