本文觀察結構之正規化相對位移振動振形(NRDVS)與基本模態振形之關聯性，進行結構物損壞程度與損壞樓層判定之可行性評估分析，並藉由NRDVS所求得之正規化層間變位角(NIDR)，作為結構快速損壞評估之依據。文中藉由不同測試類型(Benchmark D，Benchmark G)之三層樓鋼構樓房振動台試驗資料、二層樓RC校舍縮尺模型振動台試驗資料以及中央氣象局所提供之真實結構強地動監測資料，搭配OKID/ERA系統識別方法，識別結構物之基本模態振形，驗證其與NRDVS之相關性與正確性，並進行NRDVS與NIDR對結構物勁度改變下之行為探討。另外，藉由遞迴最小平方法識別方法，探討結構物於非線性行為時，如何進行NRDVS與NIDR之計算與損壞行為之關係。

A rapid damage assessment module based on the normalized relative displacement vibration shape (NRDVS) of building is proposed in this study. The fundamental mode shapes (FMSs) of structures identified by the OKID/REA method are compared with their NRDVSs to investigate the applicability and accuracy of proposed scheme. Both qualita-tive and quantitative relationships between system stiffness, NRDVS, normalized in-ter-story drift ratio (NIDR), and FMS of linear structures are studied to assess the local damage behavior. Prior to apply the proposed NRDVS module on measurements of real buildings of the Strong-Motion-Program implemented by the Central Weather Bureau (CWB) for damage detection purposes, the local damage behavior is identified based on observing the variations of NIDRs of experimental measurements of 3DOF benchmark steel frame models and scaled-down RC buildings models that were built and tested on shaking table at NCREE. Finally, the NRDVS-based rapid damage assessment module is implemented to investigate the recorded strong-motion data of Tai-Tung Fire Bureau Building located at Tai-Tung City in Taiwan.
