| Abstract: | The force-deformation curve of a reinforced concrete structure (member) with push-over analysis is used to compute its damage index. Thus, a simplified and practical method is established for seismic damage assessment in combination with capacity spectrum method. Finally, the presented approach is compared with the results using time-history analysis, and the effectiveness of this approach is verified with the help of numerical examples. |
