Abstract: A seismic strengthening method with energy dissipation brace of an existing slab-column structure in Shanghai designed according to the 74 Chinese code was introduced. Seismic response time-history analyses of the slab-column structure with energy dissipation brace were performed for 3 different earthquake time-history inputs, according to common and rare earthquake levels. And the seismic strengthening methods of columns and joints connecting the brace were presented. The results show the seismic strengthening measure with energy dissipation brace is effective.
