Echtzeitgeregelte Massendämpfer für Wolgograd-Brücke

Real-time controlled tuned mass dampers for Wolgograd Bridge

In May 2010, the Wolgograd Bridge underwent wind-induced bending vibrations with estimated amplitudes of up to 40 cm. Since November 2011, the Wolgograd Bridge is mitigated by adaptive tuned mass dampers whose frequency and damping are adjusted to the actual frequency of vibration in real-time by controlled MR dampers. This concept mitigates the bridge in the worst case similarly to and in all other cases better than passive tuned mass dampers. This improvement is achieved by approximately half the mass damper mass compared to passive tuned mass dampers which is a desirable feature for the bridge construction type.
