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. |
