In journey, to there is energy consumption effect poor for coupling beam, and repairs difficulty high cost problem after shake.
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
Being loaded in Shear-wall Connecting Beam Used, the flexural deformation of wall limb is delivered at coupling beam make coupling beam produce corresponding deformation, and then
Make damping device produce the energy of shearing lag return deformation dissipation Seismic input agent structure, protect agent structure
Safety.Present stage is installed on the damping device at coupling beam and mostly uses metal shears cut type antivibrator.But,
Metal shears cut type antivibrator is under long-term reciprocating load, especially under wind action, and its fatigue durability
Can be poor, and at coupling beam, force-mechanism is more complicated, metal shears cut type antivibrator pressure, curved, cut compound action
The easiest unstable failure.
