摘要
介绍利用大地脉动作为激振振源，测试并分析高层建筑的脉动响应信号及动力特性。阐述了高层建筑动力特性的实验模态分析法。指出专用分析仪器可以在没有大型激振设备的条件下，分析结构对大地脉动响应信号，可得到精度较高的高阶振型参数。
The measurement and analysis of the pulsation response and dynamic behavior of tall buildings taking the earth pulse as the vibromotive source is introduced. An experi- mental modality analyzing method for dynamic behavior of tall buildings is discussed.It is pointed out that,using a tailor-made analyzer instead of heavy vibromotive equipments,the constructure's response to the earth pulse can be analysed and the modality parameters of high order vibration with higher accuracy can be obtained.
