On the afternoon of 2 July 2026, the National Rail Transit Electrification and Automation Engineering Technology Research Center (Hong Kong Branch) (CNERC-Rail) at The Hong Kong Polytechnic University held an academic seminar at PolyU Y303. Prof. Judy Yang, Professor in the Department of Civil Engineering at National Yang Ming Chiao Tung University, was invited to deliver a seminar entitled "Recent Theoretical Development for Vehicle-Bridge Interaction".
In seminar, Prof. Yang introduced recent theoretical developments in vehicle-bridge interaction (VBI). Since the introduction of the VBI element in 1995, significant progress has been made in both the theoretical development and practical application of vehicle-based bridge monitoring techniques. The seminar highlighted the development of the Vehicle Scanning Method (VSM) and its technical advantages. Compared with conventional bridge health monitoring approaches, VSM requires only a limited number of sensors mounted on a moving vehicle, offering improved mobility, cost-effectiveness, and operational efficiency.
Prof. Yang further discussed advanced VBI models for identifying bridge frequencies and modal parameters, as well as their extension to the vibration analysis of railway bridges. The seminar also addressed dynamic coupling effects, three-dimensional modeling techniques, and recent experimental validations, demonstrating the growing potential of VSM for next-generation bridge health monitoring and structural assessment.
