摘要] 《建筑抗震设计规范》( GB 50011-2010)中钢结构地震作用取值略有调整，但是仍不甚合理。本文对规范GB 50011-2010中钢结构地震作用取值的问题进行了分析，并且和《建筑工程抗震性态设计通则》（试用）( CECS 160:2004)地震作用的取值进行了比较，对规范GB 50011-2010地震作用取值提出了建议。

Abstract: Although the value derived from seismic action for steel buildings defined in the Code for seismic design of buildings (GB 50011-2010) has been adjusted slightly, but it is still not very reasonable. The question of how to define the value derived from seisrmc action for steel buildings was analyzed for code( GB 50011-2010), and comparison of the seismic action for steel buildings was made between General rule for performance-based seismic design of buildings (CECS160:2004) and code GB 50011-2010. Some design recommendations have been proposed for rationalize the definition seismic action value.
