In this paper, evaluation of seismic performance of moment resisting steel frame using the shaking table test is discussed. Specimens are moment resisting steel frame with or without use of the buckling resisting brace. Three different type waves (El Centro, Hachinohe and Kobe) are inputted in the shaking table with two levels (level 1 = 25kine, level 2 =50kine). As a result of the test, we have confirmed that moment resisting steel frame with the buckling resistant brace can greatly reduce both the deformation angle and maximum strain at the edge of the beams in their mainframe. It was also shown that a capacity for energy absorption and fatigue properties of the damper decreases when set within the frame. However, the buckling resistant brace within the frame has enough capacity to resist level 2 earthquakes more than 30 times.
