提出了在频率域内用Markov过程进行大跨度桥梁风致抖振疲劳分析的计算方法。以黄浦北汊桥为例,用不同的方法对其进行了疲劳分析,计算结果表明本文提出的方法是可行和有效的,最后给出了有工程指导意义的结论。
the paper puts forward to the analysis method of buffeting induced fatigue of long span bridge by using the Markov Process method. As example of the Huangpu North bridge, using the different method to run the fatigue analysis, the results indicate the analysis method is feasible and effective. At last, the paper give a directive conclusion of engineering sense.
