The QuakeTek Rotational Friction Damper dissipates seismic energy through a rotating friction joint in braced structural frames.
QuakeTek's Rotational Friction Damper dissipates earthquake energy through friction generated in a rotating friction joint, applied in seismic force resisting systems including X-brace and tension bracing. Each damper is manufactured, calibrated, and serialized at QuakeTek's Montreal facility under its ISO 9001:2015 quality system.
The product competes for the same braced-frame seismic protection work as viscous dampers, buckling restrained braces, and other friction devices, with design guidance, modeling resources, and application examples published for structural engineers. QuakeTek positions friction dampers as an economical alternative to yielding technologies such as buckling restrained braces.
