Structural damper for protecting structures against vibrations and structure comprising such a structural damper

A structural damper for protecting structures against vibrations, comprising:

• a first pendulum with a first pendulum mass;
• a second pendulum with a second pendulum mass;
• a coupling device;
• and
• a damping device,
• wherein the coupling device is arranged between the first pendulum mass and the second pendulum mass and is configured to couple the first pendulum mass to the second pendulum mass in an effective direction of the structural damper and to allow relative movement between the first pendulum mass and the second pendulum mass in a direction of movement angled to the effective direction,
• wherein the damping device is arranged between the first pendulum mass and the second pendulum mass and is designed to damp the relative movement in the direction of movement between the first pendulum mass and the second pendulum mass (4a),
• wherein the coupling device comprises a guide element,
• characterized in that
• the coupling device has an end stop which is formed in such a way that the relative movement in the direction of movement between the first pendulum mass and the second pendulum mass is limited,
• wherein the end stop is integrated into the guide element.
