For the seismic protection of structures, the research will be focused on the development of nonlinear tuned mass dampers. These devices will be capable of mitigating structural responses and enhancing structural safety under extremely severe seismic excitation. For structural integrity assessment, the research will explore a high-rate, high-resolution video cameras for structural health monitoring. The dynamic characteristics of structures will be identified based on the recorded videos. The deformations and damage of structural elements will be detected during or after an earthquake event. The global behavior of structures can be understood by the videos, and the information in these videos will be able to determine the damage severity and locations.結構防護結構損傷評估非線性調諧質量阻尼器動態影像Structural ProtectionStructural Integrity AssessmentNonlinear Tuned Mass DamperVideos
