| Abstract: | Through comparison of the existing methods of seismic risk assessment for bridges, this paper develops the factor method of seismic risk assessment for bridges, which is applicable to the bridges of Qingdao city. Taking 123 bridges in Qingdao city as the base, we collected relative information from 243 bridges in China to determine the 13 factors and the value of each factor. Our method has been utilized in the earthquake emergency responding system of Qingdao city to simulate the potential damage of 123 bridges under destructive earthquakes. |
