Monte-Carlo was applied to generate random traffic flow after frequent, moderate and rare earthquake respectively based on sample of vehicle investigation in“907”Zhaotong, Yiliang earthquake (2012), Yunnan province, considering vehicle parameters, such as types, driving, distance, ratio in earthquake-relief campaign. Vehicle load effect was analyzed for different spans of Simply Supported Beam Bridge, then characteristic value of lane loading which ruled by 《General Code Designs of Highway Bridges and Culverts(JTG D60-04)》(China) was revised. Research can not only provide standard for rapid estimate and repair of bridge after earthquake, but also give theoretical basis for revising anti-seismic codes or guidelines in China.

In order to assess the vehicle load carrying capacity of existing bridges on the national highway G103 in Beijing, the vehicle load model for the practical traffic flow conditions needs to be determined. Based on the traffic axle load data measured by the weigh-in-motion system and the methods proposed by General Code for Design of Highway Bridges and Culverts (JTG D60-2004) and Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts (JTG D62-2004), the vehicle load parameters under practical traffic flow conditions are investigated. A typical 6-axle vehicle model with a 2-1-3 axial pattern is proposed by using the statistical analysis of total weight, axial weight, etc. The live load effects of Daliushu No. 2 Bridge, one highway bridge on the national highway G103, are analyzed using the proposed model and compared to the vehicle load model given in the Chinese code. The results show that there are great differences in the vehicle load parameters and the live load effects from the proposed vehicle load model increased by 20–50% compared with the model given by the code. The overweight vehicles are potential threats to the safety of existing bridges.

This paper takes the short and medium span bridges as examples to evaluate position of Chinese load effect partial safety factors and their combination effect. First, to get the new partial safety factors of vehicle load effects, this paper conducted a survey of the short and medium span bridges ,distinguished the similarities and differences between the standard in highway bridges from different countries and confirmed the reasonable position of Chinese standard in the world.
