Cable Vibration Mitigation Technology in Cable-stayed Bridges

Limin Sun is a professor in the Department of Bridge Engineering at the College of Civil Engineering, Tongji University. He also serves as the Vice President of the International Association for Bridge and Structural Engineering (IABSE) and the Vice Chairman of the Bridge and Structural Engineering Branch of the Chinese Civil Engineering Society. Professor Sun’s research interests include vibration control and health monitoring of bridge structures, earthquake engineering, and structural dynamics Dr. Lin Chen is an associate professor in the Department of Bridge Engineering at Tongji University. His research focuses on dynamic analysis, vibration control, and vibration-based assessments of long and slender structures including cables, bridges, and wind turbines. He is also interested in numerical methods for solving partial differential equations, particularly nonlinear wave-current interactions. He holds a bachelor’s degree and a PhD degree in Engineering from Tongji University. He has been a visiting scholar or post-doctoral researcher at Rice University in USA, Trinity College Dublin in Ireland, and ETH in Switzerland
