Through one case of storey-adding engineering, and the finite element software MIDAS/Gen to do time-history analysis, the working perfor-mance and energy dissipation performance under the earthquake waves with different strength are analyzed. The results show that the buckling-restrained brace in the storey-adding structure has good energy dissipation performance, especially under strong earthquakes, the seismic energy consumption by hysteretic deformation can ensure the structure's safety and reliability.
