The arrangement of UBB was introduced, its effects to the storey drift angle and the connection force under frequent earthquake was investigated using PKPM, and the performance of the structure equipped with UBB under rare earthquakes was analyzed using a finite element program called ABAQUS. The results suggest that UBB has significant effects to control the interstory drift and improve the connection, and the structure equipped with UBB has satisfactory performances under the rare earthquakes.Keywords: UBB; energy dissipation; FEM analysis; nonlinear time-history analysis;
