| Abstract: | The primary assessment of fatigue life at given value of failure probability for bridge-deck section is made by using the detail classification on bridge components.In order to further modify the selected probability model based on BS5400,a modified probability model suitable for fatigue evaluation at any value of failure probability is obtained.Therefore it is verified that the modified mode is practicable for reliable evaluation of the service life in bridge-deck section. |
