| Abstract: | 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. |
