vibration recessions in the high and bridge-building
- Forschungscluster "Nachhaltigkeit"
Abstract
A large number of railway, road and footbridges show a very low inherent structural damping and hence, they are susceptible for large vibrations. In order to concentrate the kinetic energy consumed from the vibrating bridge, mechanical dampers like the tuned mass damper (TMD), are properly adjusted and applied for their general design. In this project a developed model of TLCD interacting with the bridge in coupled oblique bending-torsional motion is finalized paralleled by laboratory testing. Generally, the conventional TLCD suppresses horizontal and/or torsional motions of bridges. Optimal tuning with respect to the vertical vibrations is performed analogously to the classical Den Hartog tuning of a mechanical damper (TMD)
