dc.description.abstractThis paper considers the dynamics of a human in a crouching posture (assumed during manual 10 impact hammer tests) and their influence on system dynamics. Intra-subject and inter-subject 11 statistics for the dynamics of crouching humans are determined for three and nine test subjects, 12 respectively. The average hammer operator’s undamped natural frequency was 3.49 Hz with a 13 damping ratio of 13.7%. Knowledge of the hammer operator dynamics is then utilised to 14 identify the dynamic properties of the supporting structure in an unoccupied state. The results 15 are verified on two fibre-reinforced polymer composite footbridges. Criteria for identifiability 16 of the hammer operator-structure interaction are presented and used to identify bridge 17 properties for which the hammer operator’s influence on the structure can be compensated for.en_GB
