摘要：

In this paper the behavior of three beam-column joints under cyclic loading was analyzed. The concrete joints, manufactured in a scale of 2/3 with respect to current size, were designed with reference to Eurocode 8, one made with ordinary concrete and the other two made with concrete containing 30% coarse recycled concrete aggregates as a partial replacement of the coarse natural aggregates, by taking into proper account the lower tensile strength and elastic modulus of the recycled aggregate concrete. The experimental results allowed to observe a behavior under cyclic loading of the concrete made with 30% replacement of natural by recycled aggregates quite similar to ordinary concrete.
