Yozo Fujuno, PhD, Distinguished Professor of Institute of Advanced Sciences, Yokohama National University, Yokohama, Japan. Dr. Fujino's areas of expertise include dynamics, control, and monitoring of bridges and structures, and earthquake- and wind-effects on structures. Professor Fujino has been in many bridge projects including: the Akashi Kaikyo and Tatara Bridges in Japan, the Millennium Bridge (vibration control in the UK, the Stonecutters Bridge in Hong Kong, and the Padma Bridge in Balgnadesh. He has received numerous awards; recent ones include the Medal with Purple Ribbon from the Emperor of Japan (2007), ASCE's Scanlan Medal (2011), and ASCE's George Winter Medal (2015) to name a few. He is the former president of the International Association of Structural Control and Monitoring (IASCM), and a former vice president of the International Association of Bridge and Structural Engineering (IABSE).

Lessons Learned from 30 Years of Experience in Dynamics, Monitoring and Control of Bridges. Increasingly, bridges exhibit excessive vibration due to longer spans and greater flexibility, as well as excessive loading; hence, various control remedies have been developed and applied. Based on Prof. Fujino's extensive experience, various vibration displayed by existing bridges and their control are surveyed. The importance of measured vibration responses will also be presented through several examples. It is strongly stressed that monitoring in situ performance of bridges under in-service loads is essential for not only better understanding of bridge behavior, but also better lifetime management.
