Based o the expermi e t, the hysteretic behavior, load-carryi g capacity, ductility, stiff ess a d its deterioratio process, e ergy dissipatio a d failure feature of the specmi e sw ere a alyzed systematically. The results show that the more the perce tage of the aggregate replaceme t, the poorer the seism ic performa ce of recycled co crete shearw alls; a d the seism ic performa ce of recycled aggregate co crete shearw all could be greatly mi proved by setti g co cealed braci gs i thew all.
