N2 - Statistics shows that the failures induced by human effect on system reliability cannot be ignored. The human body forms a complex dynamic system with more than one natural frequency and provides considerable damping capacities. Therefore, the human factor should be considered in the coupled system of a structure and the occupants. Monte-Carlo simulations were used to analyse the dynamic behavior of a deterministic structure coupled to users with random dynamic characteristics. Depending on the natural frequency of the empty structure, the human body dominantly acts like a mass, a mass and a damper or a damper. The influence of human body with random characteristics was verified using a laboratory beam test. Depending on the single beam experiment, the active person and passive person induces considerable damping into the coupled system. The test cases demonstrate the result from simulation. Finally, the approach is verified by a real pedestrian measurement. Both active person and passive person will change the characteristics of the structure.
