A system and method for actively damping tension members modulates the natural frequency of shape memory alloys incorporated into tension members, such as suspension ropes or cables. The frequency of the tension member can be modulated by heating the shape memory alloy, such modulation preventing potentially destructive resonance with natural exciting forces.
