Vibrating Response of the Residential Structure to Blast Based on HHT
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.
