［提要］針對(duì)銀泰中心剛度和阻尼較小的樓板系統(tǒng)的舒適度問(wèn)題，提出了樓板系統(tǒng)舒適度設(shè)計(jì)的原理和計(jì)算方法。參照美國(guó)鋼結(jié)構(gòu)協(xié)會(huì)標(biāo)準(zhǔn)（AISC標(biāo)準(zhǔn)）中樓板系統(tǒng)豎向振動(dòng)的計(jì)算公式和評(píng)定標(biāo)準(zhǔn)，對(duì)北京銀泰中心工程三座主塔樓做了舒適度分析計(jì)算。通過(guò)計(jì)算可以看出，樓板體系的剛度、阻尼和有效重量對(duì)其豎向振動(dòng)加速度起決定作用。

Vibration Design of Floor Systems of Beijing Yintai Center/Lü Zuochao, Han Hejun, Huang Jian, Li Peibin, Zhao Guangpeng, Lou Yu(China Electronics Engineering Design Institute, Beijing 100840, China)

Abstract:More and more attentions are given to floor vibrations problem because of smaller damping and lower stiffness in floor systems. The design principle and calculating method about floor vibrations are introduced and the vibrations for three tower building in Beijing Yintai Center project referring to  American Institute of Steel Construction standards (AISC standards) are analyzed. Through computing process, it indicates that the stiffness, damping and effective weight of floor systems have main influence on its vibration acceleration.

Keywords:Beijing Yintai Center； floor system； comfortable degree； baseline curve
