  • Wind breakup means for suspension bridges
    Patent number: 5287578
    Abstract: The invention provides wind flow dissipating units mountable in close relation to one another along the sidewalls of the roadway of a suspension bridge and providing pivotable plates hanging from the units in opposed parallel relation to the sidewalls, the plates being adapted to interfere with and dissipate the force of steady wind blowing toward the sidewalls so as to avoid undesirable resonance swaying of the bridge by the wind.
