The occurrence of earthquake in Mainland China is very frequent due to the collision of the Indian Ocean plate and the Pacific plate, and as the population grows and increases in buildings, the risk of exposure to earthquakes is increasing, causing casualties and damage to buildings and even national socio-economic losses. The development of catastrophe risk management in Mainland China is not yet matured enough, so this study aims to discuss how to reduce earthquake impact by catastrophe risk management.
Catastrophe risk assessment model contains event module, hazard module, exposure module, vulnerability module and financial module. In order to assess the damage of the earthquake to the structure and decide the premium of earthquake insurance, this study focuses on vulnerability assessment for establishing fragility curve. Collecting the statistical loss data of the administrative regions, and estimating the risk exposure in the area to calculate the loss exceeding probability.
In this study, the fragility curve is based on damage probability matrix collected by using the historical earthquake damage data, and compares the fragility curves of reinforced concrete frame structure with different distributions are used to calculate the mean damage ratio. Furthermore, fragility curve is updated by using Bayesian scheme with discrete prior and likelihood function. Finally, we introduce the construction scheme and process of earthquake risk exposure module and the analysis of earthquake insurance in Zhangjiakou City, Hebei Province, China. | en_US |
