报告内容简介：
Post-earthquake permanent deformation has recently been emphasized as a fundamental parameter in structural damage assessment in performance-based earthquake engineering framework. Hence, seismic-resisting self-centering structural systems, which are associated with minimal permanent deformation after earthquakes, have received considerable interest in the past decade. This talk introduces a study on novel self-centering systems taking advantage of shape memory alloys (SMA), including self-centering braced frames and self-centering base isolators. Systematic numerical and experimental investigations have been conducted, including the characterization of SMA materials and devices, the development of constitutive models, the analyses SMA-based seismic-resisting structures, the development of performance-based design methodology, and the shaking table experiment. The results indicate that properly designed seismic-resisting structures with superelastic SMAs can achieve damage-free under frequent earthquakes and design basis earthquakes, and withstand several strong earthquakes without any performance deterioration and need for repair.
