地震一直以來都是造成建築物損害的主因，在每次地震後，民眾最為關心的議題之一即為建築物的損傷程度。目前最普遍的實際做法之一，係於建築物上安裝加速度計，根據建築物受震反應訊號換算最大層間位移比，並據以判斷損傷程度。
然而，層間位移比與損傷程度的對應關係尚待釐清。目前大多採用的美國FEMA建議方式，其建築物損傷程度係根據震後建築物修復需花費之成本來定義，且未考量到台灣建築物的耐震設計不同，故其適用性有疑慮。本研究希望以民眾於震後的反應作為出發點，來定義損傷程度與層間位移比的關係。
本研究使用國震中心TEASPA資料庫的實際RC建築物之ETABS模型，根據側推分析所得到之容量曲線，將降伏點、最大強度點、韌性用盡之點對應之層間變位比來定義安全、輕微損傷、嚴重損傷等損傷程度之界線，且提供在不同層級的損傷程度下建議民眾相對應的應變作為。例如當震後結構構件尚未發生裂縫，或者僅有少數構件產生輕微裂縫時，此時建築物應為安全，則民眾可以安心繼續使用建築物。此外，本研究並探討不同樓層之層間變位比分布情形，並據以提出儀器安裝樓層建議位置與數量，及對應之門檻值折減係數。

Earthquakes have always been the main cause of damage to buildings. After each earthquake, one of the issues that people are most concerned about is the degree of damage to buildings. One of the most common practical methods at present is to install accelerometers on buildings, convert the maximum interstory drift ratio according to the earthquake response signal of the building, and judge the damage degree accordingly.
However, the corresponding relationship between the interstory drift ratio and the damage degree remains to be clarified. At present, most of the methods recommended by the US FEMA are used. The degree of building damage is defined according to the cost of building repair after the earthquake, and the different seismic designs of buildings in Taiwan are not considered, so there are doubts about its applicability. This study hopes to define the relationship between the damage degree and the interstory drift ratio based on the post-earthquake response of the people.
This study uses the ETABS model of the actual RC building in the TEASPA database of the NCREE, and according to the capacity curve obtained by the pushover analysis, defined safety, the slight damage state, and severe damage state by the interstory drift ratio corresponding to the yield point, the maximum base shear point, and the ultimate capacity point of the capacity curve. And provide the corresponding response actions for the public under different levels of damage degree. For example, when there are no cracks in the structural components after the earthquake, or only a few components have minor cracks, the building should be safe at this time, and the public can continue to use the building with peace of mind. In addition, this study also discusses the distribution of drift ratios between different floors, and based on this, proposes the recommended location and number of instrument installation floors, as well as the corresponding threshold reduction factor.
