Smart modeling of the human-structure interaction with human intervention

Abstract

The combined pedestrian and structural system is regarded as an integrated system for studying the structural vibration when the human body responds to the structural movements. A simple bipedal walking model with a time-variant damper is adopted at a given walking speed. A control force in a feedback manner is generated by the pedestrian to compensate for the energy dissipated with the system damping in walking and to regulate the walking performance of the pedestrian. The effects of stiffness. damping of the leg, and the landing angle of attack are investigated in the numerical studies. The results show that more energy must be input by the pedestrian to maintain the steady walking and relatively uniform dynamic behavior of the body mass of pedestrian in the process.
