Recent Development in Analytical Models for Earthquake-Induced Pounding between Adjacent Bridge Structures
Recent development in analytical models on earthquake-induced pounding between adjacent bridge decks are introduced. The bridge damage induced by seismic pounding in recent 30 years strong earthquakes are reviewed, various analytical models used to simulate impact effect between bridge decks are presented, which include impact-restitution approach and contact-element approach. The contact-element approach include the linear spring element model, Kelvin-Voigt element model, Hertz model, Hertz-damp model and updated Hertz-damp model. The areas required to further investigate are proposed.
