Performance-Based Engineering For Evaluation And Retrofitting Non-Ductile Reinforced Concrete Buildings Incorporating Aftershock Hazard, Ruilong Han
Dissertations, Master's Theses and Master's Reports - Open
Performance-based engineering (PBE) provides a probabilistic tool for assessing the seismic risk and performance of buildings. Only the mainshock hazard has been included in the current PBE framework, although the concern on aftershock hazard has been increased recently. This study develops methodologies to incorporate aftershock hazard into a PBE framework, and assesses the seismic risk and performance of non-ductile reinforced concrete (RC) frame buildings under mainshock and aftershock hazards. A seismic retrofit strategy for these buildings, base isolation, is also evaluated using the developed methodologies.
A methodology for synthesizing aftershock ground motions is proposed and validated to resolve the challenge …
