Abstract: I order to i vestigate the seism ic performa ce ofm id-rise recycled co crete shearw allw ith differe t perce tage
of aggregate replaceme t a d d iffere t style of rei forceme t, 5 m id-rise shearw allswere tested u der the horizo tal cyclic
load i g. 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. Through reaso able desig , the recycled co crete shearwall is able to satisfy the a ti-seism ic requ ireme ts.
