Technologies for Mitigation of Human-induced Vibrations Iin Civil Engineering Structures

Abstract

-Previous civil engineering vibration mitigation research has focused primarily on the mitigation of earthquake and wind-induced vibrations in civil engineering structures. This paper provides a review of various technologies appropriate for mitigation of much lower level human-induced vibrations in civil engineering structures. It highlights technologies or combinations thereof that have been implemented in real-life civil engineering structures as well as some reduction levels in structural responses (velocity, acceleration) that have been achieved. A review of vibration mitigation techniques with this particular focus has not been presented before. A brief background to human-induced vibration serviceability primarily in floors, foot-bridges, grandstands and staircases is provided and various technologies available for mitigation of human-induced vibrations in civil engineering structures are introduced. A detailed review of these technologies is described as well as their real-life implementations in civil engineering structures prone to human-induced vibrations. Some improvements in vibration performances of some of the civil engineering structures are also presented. The technologies that show most promise for future application in vibration serviceability of civil engineering structures are outlined.
