| Abstract: | According to characteristics of reliability analysis of existing structures, and different reference period of evaluation target, different time\|changing load model was established, and the dynamic changes of component resistance was taken into consideration. Taking the RC simple support girder on a highway as an example, the reliability index for two modes of failure, i.e., bending failure and shear failure, was calculated, and according to the correlation coefficient between the two, an analysis was made of the reliability of dynamic system of the RC girder. |
