To evaluate the dynamic characteristics of 100-meter fully-grouted reinforced-block masonry shear wall (FG-RMSW) structure, a FG-RMSW structure in construction process was tested using the ambient excitation vibration method. A total of three tests were conducted to fully understand the dynamic characteristics of this structure. Based on the structural characteristics, when the structure was built to the 10th, the 18th, and the 28th floor respectively, translation in transversal, longitudinal, and vertical directions and the vertical rotation of the structure were tested. Multiple velocity time-history and acceleration time-history records of the structure were obtained through tests. Moreover, Fourier spectra of the structure in different directions at different heights were calculated. The test results indicated that the velocity time-history was stable, without an excessive fluctuation and pulse; the reliable data could be obtained through the filtering method. Therefore, it is recommended that the velocity time-history is used as the object of analysis. By picking up the peak in the Fourier spectra, the fundamental frequencies of the structure on the 10th, the 18th, and the 28th floor were 2.76 Hz, 1.18 Hz and 0.63 Hz respectively. The higher the height of the structure, the more abundant the frequencies-spectra components are, and the higher-order modes of the structure can be displayed. The dynamic characteristics of such structures can be obtained by adopting the modal parameter identification method under ambient excitation.
