[摘要] 主要通过对现行的中国抗震规范GB 50011-2010和美国规范IBC-2009中关于抗震设防目标、场地类别、地震作用的计算方法进行比较分析，确定了其换算关系，比较了两本规范计算所得地震力的差异，最后给出了对于混凝土框架结构两本规范最大基底剪力的对照表，供工程人员参考。

Abstract: By comparing and studying the difference between Chinese code GB50011-2010 and American code IBC-2009 about the seismic design goal setting, site classification, seismic load calculation equations, a converted method has been developed to using the American code IBC-2009 to calculate the seisnuc loads in Chinese seismic zone, and a seismic base shear comparison table about concrete frame is given for engineer reference.
Keywords: seismic design; IBC; site classification; seismic response coefficient; base shear
