To test the characteristics of structural response to the blast vibration of the ground, detonative experiments were carried out on a newly constructed residential structure. By using Hilbert-Huang Transform (HHT), the spectral characteristics of vibrations on the structure are analyzed comparing to that on the ground surface adjacent to the foundation. It turns out that: vibrating amplitude could be amplified on the structure to the ground motion in the frequency bond close to the natural frequency of the structure; Amplification ratio relates to the distance between the blast hole and the structure as well as the monitoring height; while in a same height, vibration in the brick-cement wall decayed obviously when it is reinforced by carbon fiber board, vibrating amplitude in a wall covered with carbon fiber plate is lower than 1/2 times of that in a common wall.
