[提要]  對(duì)多層和高層建筑結(jié)構(gòu)抗震設(shè)計(jì)中底部剪力系數(shù)與基本自振周期的關(guān)系進(jìn)行探討，求出質(zhì)量和剛度沿高度均勻分布的三種類型結(jié)構(gòu)在不同基本白振周期時(shí)的底部剪力系數(shù)。
[關(guān)鍵詞]  基本自振周期  底部剪力系數(shù)  連續(xù)化處理

The relationship of shear force coefficient of hottom and basic natural frequency used in aseismatic design of multistory and high-rise building is discussed.  'rhe different shear force coefficients of bottom are calculated, which correspond to the different natural frequencies of three types of structures belonging to the uniform distribution of both quality and rigidity along the building height。
Keywords:  basic natural frequency; bottom; shear force coefficient; continuous processing
