Development of bridge vibration evaluation system by using physiological information

提出各种桥梁振动对人体影响的评估技术具有重要意义。本研究通过对人行天桥使用者生理信息的测量实验，提出人行天桥可使用性评价技术。在实验中，同时测量了人行桥梁和使用者的振动，研究了振动特性与生物脉冲波的关系。结果发现，随着人行天桥位移幅度的增大，用户的不满情绪也会随之增大，当用户的行走速度与人行天桥的固有频率一致时，用户的生物脉冲波也会发生较大的变化。

It is important to propose the evalutation technique of influence which a human body receives due to variety bridge vibration. In this study, the experiment to measure physiological information of pedestrian bridges user was performed in order to propose evaluation technique of serviceability of pedestrian bridges. In the experiment, the vibration of both pedestrian bridges and user were measured simultaneously, the relation of both vibration characteristic and the biological pulse wave have been investigated. As the result, it is found that the user's displeasure also becomes larger as displacement amplitude of pedestrian bridges becomes large, and the biological pulse wave of user changes a lot when user's walking pace is in agreement with natural frequencies of pedestrian bridges.
