Abstract：Based on the vehicular Weigh in Motion (WIM) data of three Expressways (Jing-Zhu, Yue-Gan and Yu-Zhan Expressway), a random vehicle flow was generated by Monte Carlo method. Then, put the random vehicle flow on a simple-supported beam to calculate the load effect by a self-made Matlab program. Furthermore, a function of maximum load effect distribution for actual operating vehicles was established by using the GPD distribution and extreme value theory to fit the tail of load effect. The reliability of the bridge structure in the conditions of actual operating vehicle loading was analyzed in the end, according to the current situation of bearing capacity of the bridge structure.
