Abstract—The coupled model of human and structure system has been developed by considering the standing human body as an elastic non-uniform column with the distributed mass, damping and stiffness. The governing differential equations of the human-beam system and the human-plate system are, respectively, derived by using the Lagrange equation. A two-section elastic column is used to simulate the vibration of the human body. The dynamic characteristics of the human-structure interaction are analyzed by the use of the complex mode theory. The influence of the human standing on the beams or the plates on vibration characteristics of the coupled systems is investigated in detail. The numerical results are compared with the experimental ones existed in the literature, good agreement has been achieved. Therefore, the reasonability and correctness of the present model have been demonstrated.
