摘　　要：分别以我国及前南斯拉夫地区典型高速公路桥梁为研究对象,采用有限元分析软件Midas/Civil对桥梁建立模型,计算其在前南斯拉夫规范和我国规范规定的汽车荷载作用下的效应值。计算结果表明,前南斯拉夫地区桥梁设计规范中汽车荷载效应与我国15规范大致吻合(差异在20%左右),在对这类桥梁进行初步设计或施工图设计时,辅以必要的调整系数,采用我国15规范对其进行结构尺寸或配筋的初拟,基本可以满足前南斯拉夫规范要求。本研究成果可为我国境外桥梁工程项目设计提供参考。In this paper,taking the typical highway bridge in China and the former Yugoslavia region as study object,the finite element analysis software Midas/Civil is used to establish model and to calculate the behavior of the bridges under the traffic loads prescribed in the Chinese Standard and the former Yugoslavia Standard.The calculation results show that the loading effect on bridges under the former Yugoslavia Standard is very similar to the effect under the Chinese Standard 2015 edition(difference is around 20%).When carry out preliminary design or Main Design for such bridges,by applying necessary and rational adjusting coefficient,it is feasible to use Chinese Standard 2015 edition to make initial estimation on structural dimension and reinforcement arrangement in order to meet the requirement of the former Yugoslavia Standard.The outcome of the research shall provide references for design of overseas bridge projects.
