Abstract

Based on a new bipedal model considered human dynamic characteristic, the dynamic equations of human-structure interaction are established by means of the Lagrange equation. Dynamic response and interaction of human and structure are studied. And effect of human dynamic characteristic on structure vibration is also analyzed. The results show that human-structure interaction will increase with a large vibration level of the structure. The mode frequencies and damping radios in any mode of structure reach the minimum and maximum respectively, while human walking pass the peak of each corresponding mode shape.

Key words
