- The uncertainty problem of ground motion input is solved properly with the proposed method based on the real-time ground motion obtained from the seismic stations;
- The amplitude, spectrum, and duration characteristics of ground motions, as well as the stiffness, strength, and deformation characteristics of different buildings are fully considered in this method, based on the nonlinear time-history analysis and MDOF models;
- Using the real-time city-scale time-history analysis and the corresponding report system, the assessment of the earthquake’s destructive power, repair time, and economic loss can be obtained shortly after an earthquake event, which provides a useful reference for scientific decision-making for earthquake disaster relief. This work is highly significant to enhancing the resilience of earthquake-stricken areas.
