Structural Motions and Vibration Mitigation

This presentation provides an opportunity to discuss structural motions and vibration mitigation strategies for pedestrian & vehicle bridges, sky-walks, link bridges, long span floors, sports and entertainment grandstands, as well as slender structures. Topics include: sources of vibration and advanced modeling techniques; vibration criteria for a range of structures; types of supplemental damping systems; project examples and how performance-based damping can be used by designers to incorporate damping into structures to enhance overall performance and efficiency. Learning Objectives -Explain the steps used to identify and analyze the sources of structural vibration in pedestrian and vehicle bridges, sky-walks, link bridges, long-span floors, and slender structures. -Understand how vibration criteria is evaluated and advanced modeling techniques are utilized to predict and assess structural performance under dynamic loads. -Design and justify the integration of performance-based damping strategies by selecting appropriate supplemental damping systems to improve structural efficiency and user comfort. 1 hr of CE credit Presenter: Jamieson Robinson
