社区需要地震脆弱性指数来确定哪些建筑物在地震中最容易受到严重破坏。为了发挥最大的价值，这些指数应该易于使用，并应根据以前地震的数据进行审查。迄今为止，已对800多座钢筋混凝土建筑物进行了震后调查，以评估哈桑和Sozen于1997年提出的地震易损性指数。这一数字包括2016年2月6日台湾地震后调查的130栋建筑。在这些调查中收集的数据包括损坏的描述和照片，结构草图和测量。数据分析表明，严重损坏和故障的概率增加，降低柱指数和壁指数（柱和壁面积的归一化措施）。他们还认为，用于区分更脆弱的结构与不太脆弱的结构的阈值的确切形式是没有什么后果的可能的成本和收益的加固计划，这个阈值可能会通知。
Communities need seismic vulnerability indices to identify which buildings are most susceptible to severe damage during earthquakes. To be of greatest value, these indices should be easy to use and should be vetted against data from previous earthquakes. To date, more than 800 reinforced concrete buildings have been surveyed after earthquakes for the purpose of evaluating a seismic vulnerability index proposed by Hassan and Sozen in 1997. This number includes 130 buildings surveyed after the 6 February 2016 earthquake in Taiwan. The data collected during these surveys consist of descriptions and photographs of damage, structural sketches, and measurements. Analyses of the data indicate that probability of severe damage and failure increases with decreasing column index and wall index (normalized measures of column and wall areas). They also suggest that the exact form of the threshold used to distinguish more vulnerable structures from less vulnerable structures is of little consequence in terms of the probable cost and benefits of the strengthening program this threshold may inform.
