This study present seismic performance assessment considering successive earthquake scenarios which are reflected relationship between predominant period and dynamic characteristic of damaged structures. Since successive seismic scenario preferentially generates without considering dynamic characteristics like the period of the damaged structure, when the difference between the period of damaged structures and the predominant period after-shock is large, it is difficult to accurately analyze the effect of successive earthquakes on structures. The target structure is conducted the dynamic analysis by the main-shock to identify how structure is damaged. When the dynamic characteristic of the damaged structure was deduced, the correlated factor is defined between the damaged structure and earthquake. The correlation factor is used to select after-shocks that can affect the structure. Successive seismic scenarios are generated through the selected after-shock and the seismic performance assessment of the structure proceeds. The seismic performance assessment between the successive seismic scenarios considering the seismic characteristics of the damaged structures and the successive scenario using the random after-shock was conducted and the effect of the after-shock selection method on the seismic performance assessment of the buildings was analyzed. To considered correlation between dynamic characteristic and characteristics of earthquake for selecting after-shock, the results of seismic performance assessment for target structure are more vulnerable and simulation time was shortened. This study will be contributed that there will be no need to configure many successive seismic scenario and more accurate seismic performance assessment will be possible.
