| description | This study introduces a method to obtain accurate results regarding bridge seismic cost and reduce structural seismic losses. A three-span reinforced concrete (RC) continuous bridges model consistent with the reality was established, and seismic vulnerability of the RC bridge was calculated via incremental dynamic analysis combined with local earthquake disaster data. Direct losses from earthquakes are calculated based on local earthquake damage condition, specific maintenance reinforcement methods, and analysis of seismic vulnerability. The indirect economic losses caused by inspection and maintenance are calculated based on local traffic volume. To reduce the effects of bridge aging and deterioration, this paper examines periodic inspection of bridges after earthquakes. By calculating the life cycle cost of structure under different inspection frequencies, the optimal time interval was determined. The results presented for this study can serve as references for the calculation of structural seismic loss and thereby provide the basis for strategies of reducing seismic loss. |
