Abstract
This paper deals with the elaborate modelling of stationary people in standing posture based on experimental and analytical results for the footbridge with the stationary people close to the center span. It is known that stationary human occupants act as dynamic mass-spring-damper systems and can change modal properties (frequency and damping) of civil engineering structures. However, there is a lack of information on the modal properties of footbridgs occupied by stationary people. Fundamental frequency obtained by a full scale measurement is compared with complex eigenvalue calculation using 2 degree of freedom ISO5982:1981 human model. Based on experimental and analytical results, it is revealed that all of the body weight does not act as TMD and that some of which act as an added mass to change the frequency of the footbridge with sand bags on the center span.
