Previous seismic retrofitting methods for high-rise buildings have focused on the strengthening of the buckling-resistant bracing of the concrete structures in the post-earthquake stadium; however, they seldom consider the energy dissipation performance of joints in different parts of the structure, resulting in a poor strengthening effect. It is necessary to study the measures for strengthening the concrete structures to improve the restoration quality of the post-earthquake stadium. In this study, the energy dissipation brace structure of concrete is reasonably arranged using the performance- and demand-based energy dissipation design methods. The buckling-resistant energy dissipation braces are installed at joints on the bottom floor of the concrete structure, and viscous dampers are installed at other joints to improve the seismic absorption and reinforcement effect of the structure. The simulation results denoted that the average top drifts of the new energy dissipation structure designed by this method was 62 and 110 mm smaller than those of the original structure under EL-Centro (NS) and Newhall waves, respectively; under earthquakes of different magnitudes, the displacement angle between the nodes of the new structure was smaller than that in the original structure. The concrete structure designed using the proposed method exhibited strong seismic absorption stability, indicating that the proposed energy-dissipating design method is effective in seismic reduction and structural reinforcement.
