AB - The flexibility and low damping of the long span suspended cables in suspension                 bridges make them prone to non-linear vibrations due to wind and moving loads. In                 this paper we consider the dynamic response of a suspension bridge due to a vertical                 load moving with a constant speed on the bridge deck. Control mechanisms are                 suggested to generate control forces to control the non-linear vibrations in the                 bridge deck and the suspended cables. A simple design is presented for the                 controller based on the feedback of the velocity measurements taken at the control                 force location. The design is made first on a linear model before applying it to the                 actual non-linear system. The method is applied on three different types of control                 mechanisms. Comparison between the controlled responses using the three controllers                 indicates that, in addition to the method of designing the control actions, the                 feasibility of the active control depends mainly on the type of the control mechanism.
