This study addresses the economic and safetyneeds of seismic retrofitting for existing buildings byinnovatively integrating rubber gaskets and aluminum-rubber composite gaskets into friction dampers (AFC)combined with CLT panels for reinforcing reinforcedconcrete frames. Through cyclic loading tests, thehysteretic performance, energy dissipation efficiency,and temperature characteristics of aluminum, rubber,and composite gaskets were systematically compared.Experimental results show that the composite gasketeffectively resolves eccentricity issues while maintainingthe high strength of aluminum, achieving superior energydissipation efficiency (μ = 0.18) without damage to therubber layer. Although rubber gaskets offer economicbenefits and mitigate eccentricity effects, they are prone tofailure under cyclic loading. This system provides a novelsolution for seismic retrofitting of wood-concrete hybrid structures in earthquake-prone regions of Russia.
