英文摘要: The exposure model is a key component of a seismic risk model, which captures the spatial distribution of population and built assets along with their structural characteristics and valuation that are required for seismic risk assessment. Current and available exposure models for China have various limitations that make them less suitable for use in risk assessment, including low spatial resolution of building inventory and the limited identification of key structural characteristics. This study describes the development of a residential buildings’ township-level exposure model for mainland China, containing information about the geographical distribution, structural characteristics, age, ductility, number of stories, number of dwellings, average built-up area, and replacement cost at the township level. This exposure model is intended to be used for risk assessment and to support emergency planning, risk management, and decisions. The geographical distribution’s detailed analysis of the building typologies, heights, and construction vintage at the national, regional, and provincial levels is provided to better aid in understanding country exposure. The results indicate that based on the method, flow, and data from the 6th National Population Census of the People's Republic of China, we can generate key information used for seismic risk analysis, representing a significant step toward a better understanding of risk due to seismic hazards in mainland China. © 2021, The Author(s), under exclusive licence to Springer Nature B.V.
