A kind of U-shape steel jacket is proposed in this paper for connecting the energy dissipation braces to frame joint,with which the damping force can be applied directly on the joint.Two full-scale rein-forced concrete portal frames are made and U-shape steel jackets are applied to connect steel braces to the joints of beam and column.The specimens with two kinds of installation forms of energy dissipation brace are tested by high-speed pseudo static test.The shows of the specimens test indicates that the proposed U-shape steel jacket works well and can ensure the integrity and safety of the joints when the damping force exerts.
