中文摘要：

在研究环境振动下结构和人体的动力响应时，有必要考虑人与结构的相互作用。根据国际标准ISO5982规定的不同姿势下的竖向人体动力模型，建立了具有非经典阻尼的人与结构耦合运动方程。将运动方程转化为空间状态方程，从而实现了方程的解耦。在国际标准ISO2631的基础上，提出了由小波包变换求得频带能量，进而评价人体舒适度的方法。以一幢在轻型轨道附近的10层住宅为例，分析了不同人数和不同姿势的人体下的人与结构体的动力响应。结果表明：对于一般的质量和刚度分布均匀的结构，随着人数的增加，结构的减振效果越明显。随着楼层的增加，结构的减振程度和人体舒适度都不断降低。环境振动下坐姿人体的反应最显著，而立姿人体的次之。

英文摘要：

The problem of human-structure dynamic interaction need to be considered when the dynamic responses of structure and human occupants under ambient vibration are studied. The vertical human body models with different postures are selected according to ISO5982, and the dynamic coupling equations with non-classical damping for structure and human are established. The equations are decoupled by spatial state model method. A new method for evaluating human comfort evaluation is presented by obtaining the frequency-band energy with wavelet packet transform based on ISO2631. A 10-story building near the light rail transit system is studied to analyze the dynamic performance for different numbers of human occupants and different body postures. The results show that for the structure with even mass and stiffness, the vibration reduction effects of floors are more obvious if the numbers of human occupants increase, and the vibration reduction effects and human comfort decrease for higher floors. The discomfort of the seated human body is most significant. The comfort evaluation method in this paper is reliable and convenient, which could be used as a supplementary method.
