Viscous Shear Damper Design Methods And Engineering Applications

In this paper, phenomenon and mechanism of wind-induced vibration and parameter of cables are particularly introduced, as well as characteristic of all kinds of vibration-controlled measures wildly adopted. Then, the program based on complex eigenvalue method was employed to investigate the influence of three parameters on vibration-controlled of cables. Final, in term of character of VSD which is strongly dependent on temperature, the method based on lowermost damper of first order vibration-controlled aim at design tiptop temperature and checked at minimum temperature is presented, in which available shear area of damper is calculated. Through being applied in bridge, this method is proved right, reliable and having the value of practice.
