    • Abstract
  • The simulated earthquake experimental study on a large desulfurization tower was carried out using shaking table test. A 1:15 reduced-scale thin-walled steel structure model of the desulfurization tower was designed for testing and the dynamic responses of the model were discussed. The responses of peak acceleration were studied under a sine wave, Tianjin wave and Hyuga seismic wave in various angles and the most unfavorable input angle was analyzed. The results show that the influence of the input angle of an excitation wave can not be ignored, the maximum influence is in the direction of 30° and the minimum is in the direction of 60°. The complexity of the thin-wall desulfurization tower can affect the dynamic characteristics of the structure to a great extent. The weight of the tower top is one of the main factors causing the distribution of peak acceleration uneven in tower height.
