摘要

The dynamic characteristics of a mega-frame model structure under ambient vibration was tested and analyzed. The article compared two methods of modal parameter identification: the Ibrahim Time Domain Technique (ITD) in time domain, and the Fast Fourier Transform (FFT) in frequency domain. Then verified the similar relation by checking the test analysis results on the calculation results of the original structure.
