| The main purpose of this paper is to analyze the factors which affect the effect of the viscous shearing damper used to control the vibration of cables of the cable stayed-bridge. First, the common phenomenon and characteristics of the wind-induced vibration is described. Then, the classification of damp and the mechanism by which damp can diminish the vibration is introduced. According to the research status of the viscous shearing damper at home and a lot of kinds of the cases which are met with during the course of vibration-induce designing. Compared to the computation program developed by the research group, the finite element program—ANSYS is adopted, thevibration-induce effect which the viscous shearing damper can achieve is analyzed. At the same time, the influence of the cable structure, the temperature, and the position of viscous shearing damper on the effectiveness of viscous shearing damper is analyzed. Finally, experiment is carried out on AnQing Yangtze bridge to testify the correctness of the effect of viscous shearing damper under all kinds of cases and the designing method of viscous shearing damper. |
