This research opportunity focuses on improving the state-of-the-art concerning the seismic design and assessment of new and existing buildings, with an emphasis on performance-based seismic engineering. Opportunities include the following: (1) developing improved nonlinear modeling capabilities for seismic structural evaluation; (2) computing the collapse probability of new and existing buildings using incremental dynamic analysis or other probabilistic approaches; (3) developing cost-effective solutions to mitigate earthquake vulnerabilities in existing buildings; (4) quantifying the impact of earthquake selection and scaling procedures on building design and assessment; (5) investigating the effects of loading protocols on the performance of structural components, such as eccentrically braced frame link beams, and conducting experimental research to fill in knowledge gaps; (6) quantifying the effects of uncertainties on the prediction of structural response, particularly focused on the uncertainties inherent in experimental measurements; and (7) developing and testing new applications for smart materials (e.g., shape memory alloys) for seismic performance enhancement.
