［摘要］為滿足完成國內(nèi)合資及海外項目工程的需要，依據(jù)國標(biāo)抗震規(guī)范GB50011—2002和美標(biāo)UBC97規(guī)定的地震作用靜力計算法，比較了結(jié)構(gòu)在多種場地類型和地震烈度下的基底剪力計算結(jié)果。分析表明，在絕大多數(shù)情況下，框架結(jié)構(gòu)國標(biāo)地震基底剪力大于UBC計算值，最后給出了結(jié)果對比表以方便工程應(yīng)用。

Abstract:To meet the need of executing domestic and oversea projects, based on the PRC code GB50011—2002 and American code UBC97 regulations, the seismic base shear of structures under the different soil classifications and seismic accelerations is compared. The analysis shows, the PRC code give greater base shear than UBC in most cases. A comparison table is given for engineering application.
