摘要

基于考虑人体动力特性的新型双足模型，采用Lagrange方程建立了步行过程中人与结构相互作用系统运动方程。研究了人与结构各自的动力响应及其之间相互作用，并通过对比说明了新型双足模型反映的人体动力特性对结构振动的影响。结果表明：人与结构相互作用增大结构动力响应；行人经过结构各阶模态振型波峰时，结构各阶模态频率和阻尼比分别达到最小值和最大值。

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.
