摘要
After a brief introduction of the framework of seismic risk assessment (SRA), the current state of SRA in China is presented in five parts: the vulnerability assessment of structures, SRA methodology, earthquake loss estimation, disaster management and laws, and geographical information system (GIS), with emphasis on current Chinese practice. The vulnerability matrices used are mostly from recent earthquake experiences in China, such as the 1985 Haicheng Earthquake and the 1986 Tangshen Earthquake, especially for structures such as the adobe and unreinforced masonry buildings. For SRA, different requirements are required for different scales of exposures, e.g., global scale, regional scale, city scale, and individual scale. Simple and average conditions are used for exposure estimation and seismic hazard assessment (SHA) for the global scale, and very specific and detailed conditions for the individual scale, such as for a specific engineering project. In China, there are some standardized requirements for SHA and SRA in addition to seismic design codes, which are followed.
