| Abstract: | In reference 5], the relation between the magnitude of main shock with those of aftershocks has been quantitatively determined through statistics, and the modified model of main shock and aftershocks ground motion has been established as well. Based on that paper, by taking artificially generated earthquake records as incoming ground motion and using the time-history method for elasto-plastic analysis of earthquake structural response, the method for response and damage analysis of reinforced concrete structures under main shock and aftershocks has been presented in this paper. Through the numerical calculations of a two-story reinforced concrete structure and a eight-story reinforced concrete structure, the effect of aftershocks on the response and damage of structures have been demonstrated. |
