摘要:
为精确模拟汽车荷载效应样本分布的尾部形状,利用基于Pareto分布的超越阈值(POT)模型计算样本频率分布函数;然后,采用尾极值指数检验法检验样本的厚尾性,采用峰度法检验样本的尖峰性和计算样本阈值;最后,基于经典极值理论计算汽车荷载效应极大值分布和设计标准值.对某大桥111 d的动态称量(WIM)车辆荷载效应进行极值估计,结果表明:跨径小于等于16 m的车辆荷载效应符合尖峰厚尾分布,适合采用文中方法计算车辆荷载效应极值.
Abstract:
To accurately simulate the tail shape of vehicle load effect distribution, the peaks over threshold(POT)model based on Pareto distribution was used to fit the frequency distribution of the vehicle load effect sample first. And then, the tail extremum index method was adopted to test the fat-tailed traits of the vehicle load effect sample, and the Kurtosis coefficient method was used to test the Kurtosis traits and the threshold of the vehicle load effect sample, respectively. Finally, the maximum value distribution and design standard value of vehicle load effect were calculated based on classical extreme value theory. The proposed method was used to estimate the maximum load effect of the weigh in motion(WIM)vehicle in 111 d of a bridge. The results show that the vehicle load effect of 16 m is consistent with the peak and fat-tailed distribution. The proposed method is suitable to calculate the extreme value of vehicle load.
