中文摘要：

针对由人-结构系统的水平相互作用问题,建造了用于人-结构耦合振动研究的钢框架平台。共六人参加此次试验,并测试了添加混凝土质量时结构的动力特性。研究表明：当人静止站立于平台结构上时,与空平台结构相比,人-结构系统的共振频率会降低,但与重量相当的质量块-结构系统相比,降低幅度相对较小,表明在水平方向,不可以简单地将成人等效为相当重量质量块附加在平台结构上;最后,提出了人体前后向的等效附加质量模型,来模拟人对结构水平振动频率的影响,并通过试验验证了此模型的有效性。

英文摘要：

A steel framed structure was designed for studying the human-structure coupling vibration in lateral directions. Six individuals joined the tests by standing on the structure and the structure with concrete blocks was also tested. An impact loading was applied in the lateral directions of the structure for the cases including pure steel frame, an individual standing on the structure, and a concrete block laying on the structure. It was observed from the measurements that the human and concrete block could low the resonance frequencies of the entire system. However, the resonance frequency of concrete block-structure system was much lower than that of the human-structure system in the lateral directions. This observation indicated that a standing body could not simplified as a mass. Therefore, an equivalent additional mass model of human body in front and back directions was developed to consider the effects of human to vibration of the structure. The validity of this model was confirmed by experiments.
