Following the fundamental methodology study in the first year, the Central Taiwan Science Park will be used as a demonstration example to exhibit the performance and practicability of the proposed system. Based on the occurrence of seismic events, prediction, evaluation and diagnosis can be rapidly launched. In the first stage, the peak round acceleration (PGA) can be predicted and compared with the on-site design PGA to roughly estimate the possible structural damage. The peak floor acceleration can then be evaluated by combining the rapid structural response module and the seismic parameters supported in stage 1, and the floor damage probability can also be provided. Finally, the damage condition and orientation can be diagnosed by the long-term monitoring database and the developed structural health monitoring techniques. It is hoped that the developed AEEW system can be implemented widely in the near future.地震預警技術研發結構受震反應快速評估結構健康診斷與損傷評估earthquake early warning technologyrapid structural performance evaluationstructural health monitoring地震防災監測預警技術研發與測試-地震防災監測預警技術研發與測試
