The purpose of this study is to grasp the possibility of using recycled aggreate concrete in the reinforced concrete structures. Using recycled aggreate in full to a beam member, the seismic performance of this member was compared with that of normal concrete member through the tests concerning flextural, shear and bond. The parameters of the tests were failure mode and concrete compressive strength. From the test results, the failure mode can be predicted and the seismic performance of RC members with recycled aggregate concrete were the same as those of the normal RC members. Futheremore, it was found that the strengths of the RC members with recycled aggregate concrete can be calculated as a safty side by previous strength equations.
