Key Lab ofU rban Security and D isaster Engineering, MOE, Beijing 100124, China) Abs tract: To ach ieve the seism ic perform ance of recycled concrete shearw alls, three 1/ scaled modelsw ith dif ferent percentage of aggregate rep lacem ent, includ ing one natural concrete shearw al,l one recycled concrete shear w allw ith 100% recycled coarse aggregate and one recycled concrete shearw allw ith 100% recycled coarse and fine aggregate, were tested on the shaking table. The testing process included elastic, crack ing , and failure stages of the model structures. Dynam ic characteristic and dynam ic response of the structures at d ifferent stagesw ere studied and alsomade the comparison betw een failure patterns of models. By comparing the test resu lts show that the seis m ic perform ance of the recycled coarse aggregate concrete shearw all is close to the seism ic performance of the natu ral concrete shearw al
