Buckling restraint braces have resistant capability to both tension and compression because of blocking buckling phenomena. On the other hand, non-compression braces resist no compression and only tension by function of a wedge device. The buckling restraint braces do not possess such unique capability. Shaking table tests on one story frame with the brace arranged in z-type were carried out to verify one direction vibration and constant convergence. In this paper, shaking table tests and numerical analysis on two stories frame are carried out to obtain the same results as the one story tests.
