The active beam link of accentric support framework easily produces destruction, and reason is that active beam link force-mechanism is more complicated,
Bear simultaneously draw, curved, cut compound action, and in earthquake, have bigger reciprocal plastic deformation so that shake
Rear replacing, reparation inconvenience, and relatively costly.
Along with development and the application of energy-dissipating and shock-absorbing technology, energy-consumption shock-absorption device is pacified by the most existing many scholars
It is loaded in accentric support framework, substitutes traditional active beam link, utilize existence at accentric support active beam link
Relative deformation so that damping device produces the energy of shearing lag return deformation dissipation Seismic input agent structure, protects
Protect the safety of agent structure.The damping device that at present Chinese scholars uses based on metal shears cut type antivibrator,
But this type of antivibrator bear at the same time draw, curved, cut easy unstable failure during compound action, anti-under big shake
And bring certain potential safety hazard to eccentrical braces.
