简要回顾了日本钢筋混凝土建筑物地震易损性评价标准的发展。损坏的统计数据表明，即使在世界上破坏性的地震后，在相对较小的比例的现有建筑物中观察到严重的损坏。因此，有必要采用一个简单的筛选程序，从现有建筑物中识别出这些脆弱的建筑物。在讨论了利用简单单自由度体系进行地震易损性评估的原理之后，讨论了其在多自由度体系和不规则结构中的应用。介绍了符合日本现行设计规定的一般程序。
The development of seismic vulnerability evaluation standards for reinforced concrete buildings in Japan is briefly reviewed. Damage statistics are shown to indicate that severe damage was observed in a relatively small percentage of existing buildings even after damaging earthquakes in the world. Therefore, a simple screening procedure is necessary to identify such vulnerable buildings out of the existing building stock. After discussing the principles of seismic vulnerability assessment using a simple single-degree-of-freedom system, applications to multi-degree-of-freedom systems and to structures of irregular configuration are discussed. A general procedure consistent with the present design provisions in Japan is introduced.
