  • In order to effectively evaluate existed bridge reliability, the effect of bridge service time on bridge reliability was considered, some simplified formulas for calculating bridge reliability index were deduced based on the dispersed stochastic resistance and load effect of bridge, the effects of its resistance degradation model, load increasing tendency and service life on bridge reliability index were studied.Calculation result shows that bridge reliability index decreases with the increase of bridge service life, and it is sensitive to the resistance degradation mode and load increasing tendency of bridge.
