真實結構之動態反應訊號量測與訊號處理為結構安全監測與損壞識別的首要過程，為能夠快速提供安全監測與識別研究所需之各種資料，進一步達成自動化判別與快速預警功能，本論文應用最先進訊號自動處理軟硬體技術，建立一座與中央氣象局(Central Weather Bureau, CWB)現有裝設於結構物感應器並聯運作之「即時建築物損壞指標與預知警報系統(Real-Time Structural Damage Assessment and Warning System, RTSDAWS)」。於西元2006年12月26日恆春地震時，RTSDAWS和中央氣象局於國立成功大學雲平大樓同步監測到結構物加速度反應訊號，經由比對和驗證RTSDAWS整體流程在實際應用的可行性。

為建立RTSDAWS快速識別結構物損壞方法，藉由結構物剛心位置為判斷損壞的依據，以扭轉耦合剪力屋架結構運動方程式，將方程式推導為剛心識別公式，由結構物受強震的反應歷時識別結構物剛心位置，以剛心位置受強震移動的相對關係，評估結構物損壞位置。並應用SAP2000分析軟體建立單層樓和多層樓模型，將各模型單一柱斷面積折減時受震的反應歷時，探討剛心識別方法的可行性，進一步採用台東消防局破壞前和破壞後量測資料，驗證剛心識別在實際應用的可行性，以提供未來實際應用和RTSDAWS識別模組之參考。

Correct and fast response measurements of structures are the first procedure of structural health monitoring and damage assessment. In order to provide necessary information required by different identification modules rapidly, a Real-Time Structural Damage Assessment and Warning System (RTSDAWS) running in parallel with the existing building arrays installed by Central Weather Bureau (CWB) in Taiwan is developed in this study. Based on up-to-date data-acquisition and signal-processing technology, required signal manipulation modules and a Real-Time Structural Response Integrator (RTSRI) are embedded in the software of this system to perform the automatic structural response manipulating function. The experimental results from shaking table test of a benchmark model in National Center for Research on Earthquake Engineering (NCREE) in Taiwan are chosen to verify the proposed system and it has been implemented at the University Administrative Building (Yun-Ping Building) of National Cheng Kung University for further verification.

Since the onest of column failure will cause the redistribution of stiffness that is reflected by the movement of location of center of rigidity (CR), this idea can be used as the indication of failure. A preliminary identication module is deveioped and embedded in the RTSDAWS system in order to achieve rapid assessment requirement. Based on the equation of motion of torsionally-coupled (TC) shear type building, the identification scheme id derived by utilizing the measured acceleration record together with displacement response integrated through RTSRI directly. The feasibility of this module is investigated and verified by numerical simulation through the response of single-story and multiple-story TC models generated by SAP2000 computer software. It shows that the CR moves toward the opposite direction of which the damage developed. This module is then applied to the damage assessment of the Taitung Fire Department Building, located in Taitung City. The results agree well with the reconnaissance report of visual inspection after the Beinan Earthquake on April 1, 2006.
