Claim:
1. Method of damping the vibrations of at least one pair of stay cables of a stay cable array of a civil engineering structure, in which the stay cable array provides support and stability to the structure, and in which the stay cables of said pair are linked by a damper to damp vibrations between the at least pair of stay cables, the damper having a first stiffness in response to tensile stress and a second stiffness in response to compressive stress due to movement of one stay cable relative to another stay cable of the pair of stay cables of the stay cable array, the first stiffness being greater than the second stiffness, and in which the first stiffness is at least 1.2 times greater than the second stiffness, and in which the second stiffness is almost zero.
