摘　　要：对比了中欧抗震标准中有关钢结构抗震设计的若干条文，包括抗震设防目标、场地分类、抗震设计反应谱及抗弯框架结构的设计地震作用。结果表明：在对场地条件以及地震作用的计算方法进行一定换算的基础上，对于D类场地下不超过50m的工字形截面抗弯框架结构，欧洲抗震标准中柱的设计地震作用基本上要高于GB50011—2010，梁的设计地震作用基本上要比GB50011—2010低10％～40％。There are some differences between the Chinese seismic design code （GB 50011--2001） and Eurcode8 （Design of structures for earthquake resistance --Part1-1：General rules, seismic actions and rules for buildings EC8） in the seismic design of steel structures. In this paper, some provisions about the seismic design of steel structures, including the seismic design objectives, site classifications, seismic design spectrum and the seismic force for moment resisting frames are compared. The results show that, based on the simplified treatment of site classifications and calculation methods of seismic force, for site type D and the I-shaped section moment resisting frames not higher than 50 m, the seismic force of column in EC8 is higher than that in chinese code, and the seismic force of beam in EC8 is 10%-40% lower than that in chinese code.
