  • Friction damper for a building structure
    Patent number: 10563418
    Abstract: A multi-load friction damper includes opposed gusset-side plates defining a slip channel. First and second brace-side plates are received within the slip channel and form first and second frictional engagements respectively. The frictional force of the first and second frictional engagements may be different. A multi-layer friction damper includes a central gusset-side plate and first and second outer gusset-side plates. First and second brace-side plates are received between the central gusset-side plates and the first and second outer gusset-side plates to form first, second, third and fourth frictional engagements. A multi-damper assembly includes a gusset engagement member and brace engagement member. A plurality of friction dampers extend between the gusset engagement member and the brace engagement member.
