摘要
结合对南昌赣江大桥南桥第 1 0孔桁梁桥的疲劳寿命评估 ,介绍了采用蒙特卡罗法模拟疲劳荷载的情况 ,随后对比了实测数据与模拟数据 ,确定模拟数据可以用于实际疲劳寿命评估。利用模拟数据分析了赣江大桥的疲劳损伤的概率分布情况 。
The paper is based on the fatigue life evaluation of the 10th span of the Ganjiang River Bridge in Nanchang The fatigue load is simulated with the Monte Carlo Method and is proved to be compatible in the evaluation after compared with surveyed data It is confirmed that the simulated data can be used to evaluate the actual fatigue life The probability distribution of the fatigue damage of the bridge is analyzed using the simulated data,thus defining the fatigue life of Ganjiang River Bridge at the given probability
