【 摘 要 】
The operating mechanisms of movable bridges are subjected to various types of fluctuating loads which may induce fatigue damage. Wind load acting on the bridge deck ? when the bridge is open ? is one of the important load types. A wind load model is proposed which can be used in the fatigue design verification. The model is based on wind statistics. It is presented as a Markov matrix that gives the probability of the combinations of mean wind loads and wind load fluctuations. The model will be implemented in the new version of the standard NEN 6786.
