[摘要] 主要通過(guò)對(duì)現(xiàn)行的中國(guó)抗震規(guī)范GB 50011-2010和美國(guó)規(guī)范IBC-2009中關(guān)于抗震設(shè)防目標(biāo)、場(chǎng)地類(lèi)別、地震作用的計(jì)算方法進(jìn)行比較分析，確定了其換算關(guān)系，比較了兩本規(guī)范計(jì)算所得地震力的差異，最后給出了對(duì)于混凝土框架結(jié)構(gòu)兩本規(guī)范最大基底剪力的對(duì)照表，供工程人員參考。

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
