2、柱的重量，各樓層墻體的重量，然后按以樓層為中心上下各半個(gè)樓層的重量集中于該樓層的原則計(jì)算各質(zhì)點(diǎn)的重力荷載代表值。水平地震作用計(jì)算還涉及結(jié)構(gòu)的自振周期，本工程采用假想頂點(diǎn)位移法確定。水平作用下內(nèi)力及位移分析均采用D值法計(jì)算。一一重力荷載代表值計(jì)算重力荷載代表值計(jì)算1.1.各層梁、板、柱自重標(biāo)準(zhǔn)值見(jiàn)下表：各層梁、板、柱自重標(biāo)準(zhǔn)值見(jiàn)下表：柱重力荷載標(biāo)準(zhǔn)值層數(shù)柱編號(hào)截面尺寸mm凈高mgk(kNm)數(shù)量GkikNGki總和kNKZ14505003
