文摘

Effect of pavement maintenance cycle on steel bridge fatigue reliability is studied. Effect of dynamic load of fatigue truck on stress range of bridge members is studied. Bridge fatigue reliability decreases rapidly under truck loads in very poor RSC. A new procedure to determine steel bridge pavement maintenance cycle is developed.
