Due to its vertical liveliness, the Warwick Bridge is a unique platform for studying pedestrian interaction with perceptibly vibrating decks. The VICON motion capture system is being used on the bridge to monitor kinematics of the human motion while walking over both lively and an equivalent rigid structure. Figure 1 shows a test trial on the lively deck as well as the corresponding walking model reconstructed in Nexus software. Quantifying kinematics of the human movement will allow to identify the stepping strategy applied by people while walking over lively decks, and its influence on vibration performance of the structure. The experimental data will enhance our understanding of pedestrian-structure interaction and they will help developing performance based cost effective design procedures applicable to slender structures.
