中文摘要：

文中研究和对比中国规范和德国规范在设计汽车荷载方面的差异,分别从汽车荷载模式、加载模式,以及冲击系数等方面介绍了中国14规范、中国04规范和德国规范关于设计汽车荷载的规定.同时,对这3种规范下的中小跨径桥梁和大跨桥梁的设计汽车荷载效应进行了对比.研究发现,与中国规范相比,德国规范对于中小跨径桥梁的设计汽车荷载效应相对偏小,而对于大跨桥梁的设计汽车荷载效应则相对较大.

英文摘要：

In order to study the Chinese code and German code in the design of vehicle load differences, the provisions on the design vehicle load in Chinese code of the year 2004 and 2014 and Germany code are separately presented in the aspects of vehicle load mode, load pattern and impact coefficient, etc. Moreover, the comparison on the effects of design vehicle load is conducted among 60/30 class of load- ing in Germany code and Highway Class I loading in the two versions of Chinese code in small, medium and long span bridges. It is observed that the Germany code has a relatively small effect of the de-sign vehicle load for small and medium span bridges, and yet has a relatively large effect for long span bridges.
