This research opportunity focuses on improving the functional recovery of buildings and infrastructure systems after natural hazards. Opportunities exist for (1) developing a framework for design of buildings and infrastructure systems to meet recovery-based objectives (functional recovery framework), (2) developing design criteria for achieving recovery-based objectives, (3) computing the collapse risk of new and existing buildings and infrastructure systems, (3) developing improved nonlinear modeling capabilities to evaluate the response of new and existing structures, (4) applying the Fiber Reinforced Polymer (FRP) retrofit design to improve the performance of existing structures, (5) studying the feasibility of using high strength materials in reinforced concrete structures for seismic applications, (6) quantifying the impact of earthquake strong ground motions, their characteristics and their selection on building design and assessment, structures, (7) conducting analytical and experimental studies on reinforced concrete structural components in new, existing, and retrofitted/repaired structures, (8) quantifying the effects of uncertainties on the prediction of structural response, and (9) evaluating the effectiveness and conducting cost assessment analysis of available retrofitting approaches to mitigate earthquake vulnerabilities in existing buildings, especially nonductile systems.
