Joint Organizers

Jointly organized by HKIE Civil Division and NTU Alumni Association (Civil & Geology) in Hong Kong and supported by Department of Civil and Environmental Engineering, The Hong Kong Polytechnic University



Dr. Y. B. YANG, Distinguished Professor of Department of Civil Engineering of National Taiwan University, and Chairman of Accreditation Council of the Institute of Engineering Education Taiwan (IEET).



Programme Highlights

Conventional vibration tests for measuring bridge dynamic properties require on-site installation of the measurement equipment, particularly the vibration sensors, which is generally costly, laborious, and inconvenient. In 2004, the idea of using a moving test vehicle to extract the dynamic properties of the bridge was first attempted by Yang and co-workers. In the literature, the conventional approach is known as the direct approach, as the sensors are directly mounted on the bridge, and Yang’s approach as the indirect approach, as the sensor is mounted instead on the test vehicle. The latter has the potential of becoming an efficient and movable tool of measurement for bridge dynamic properties, which is especially useful: (1) when a number of bridges are to be monitored in regular intervals for the purpose of maintenance, or (2) when a large number of bridges are to be examined in a short time, say, after a major earthquake.

The idea proposed by Yang has been followed, verified, and expanded by researchers worldwide, especially to the area of damage detection of bridges. In this seminar, the progress that has been made since 2004 at the Civil Engineering Department of National Taiwan University will be reported. Particular emphasis will be placed on the improvement along the two lines of hardware and software, which form the backbones for the technique to be successful. Finally, concluding remarks will be given concerning the future development of the technique for it to become a reliable, mature, and accurate tool.
