EXPERIMENTAL STUDY OF LATERAL VIBRATION OF HUMAN-STRUCTURE SYSTEM

To study the impact of human body in the stationary state on the lateral vibration performance of structure, an experimental platform is built up and the horizontal natural frequency of the vibration and the damping ratio of the mass-structure system and the human-structure systems are tested and analyzed. Two static lateral coupling models of the human-structure system are used, to obtain the range of the lateral vibration frequency of human body. It is shown that the human body in the stationary state could not be simplified as a mass block as in a mass-springs-damping system to evaluate the impact of the human body on the lateral vibration performance of the structure, and a mass-spring-damper system should be adopted with the human body as a rigid mass. Based on the experimental data and the human-structure coupling model, the ranges of the lateral frequency and the fore-and-aft frequency of the human are calculated, with the results of 0.236~3.748 Hz and 0.194~5.32 Hz, respectively.
