| Abstract: | Models of reliability analysis were established and calculation methods of the models were discussed with consideration of load history for the evaluation of existing bridge structures. Using the methods presented, the reliability of load-bearing capacity for an actual reinforced concrete bridge was analyzed and es?timated. Results of the analysis showed that the influence of load history on the increase in reliability of the bridge could not be neglected. |
