Introduction

    The Research Division on Structural Health Monitoring and Vibration Control in the Department of Bridge Engineering, Tongji University, was established in 2001, by Dr. Limin Sun. It is also recognized as a subinstitute of State Key Laboratory for Disaster Reduction of Civil Engineering. Researches of the division have been funded by Natural Science Foudation, Ministry of Education, Ministry of Science and Technology, Ministry of Transportation of China, Science and Technology Commission of Shanghai Municipality, Ministry of Transportation of Jiangsu and Hebei Provinces and so on. Our research outcome has been applied to many major projects, including the Donghai Bridge and Yangtze River Bridge in Shanghai.
