A Review of Studies on the Seismic Vulnerability of Structures in China

The performance-based seismic vulnerability analysis is the basis for evaluating the seismic reliability of structures, which is of great significance to the prediction of seismic damage and the establishment of seismic design codes based on the reliability theory. In this paper, a comprehensive review of the methods of seismic vulnerability analysis, the current research status, and the remaining problems in this field is presented. Firstly, the methods of structural seismic vulnerability analysis are categorized, and the advantages and disadvantages of each method are summarized, and the research progress in this field is discussed in detail; Finally, it is concluded that the research on the seismic vulnerability of structures in China has not yet produced research results of practical engineering significance. A set of more effective seismic vulnerability analysis theories should be established to directly guide the performance-based seismic design of structures by reasonably and accurately quantifying relevant factors such as ground shaking input parameters and performance level damage indicators.
