Patent ID: 8307585

Claim:
A device for damping movements of structural and non structural elements in civil engineering structures, the device comprising: at least two members, a pin extending through each of the at least two members so as to provide a rotational joint, a piece of a visco-elastic material arranged between the at least two members in said rotational joint for visco-elastic damping of relative movement between the at least two members, each end of the visco-elastic material being fixed and non-slidably attached to an adjacent member or material in said joint, a clamping device configured to clamp the at least two members together, so as to provide a clamping force applying a compressive force against the visco-elastic material, and a connecting device configured to connect each of the at least two members to respective ones of the structural elements, and a piece of a friction material arranged between and in contact with a first one of the two members and the visco-elastic material for a combined frictional and visco-elastic damping of relative movement between the at least two members.
