Since the outer and inner layers of the steel plates connect to different stories of the structure, the drifting between stories due to wind or earthquake will cause the steel plate to move to opposite direction. Thus, the viscoelastic material between the steel plates will be forced to deform and dissipate the energy. Viscoelastic material was initially designed for vibration control in the aerospace industry. When the viscoelastic material deforms, the kinetic energy is transformed to strain energy and heat, which is then dissipated.
Upon request, our Technical Department can tailor KVM VD with:
Max Out-Put Force: 1,000 kN
Max Displacement: 60 mm
