[提要]  用底部剪力法計(jì)算帶屋面突出物的高層建筑的水平地震力。對(duì)于屋面突出物，給出了有別于主結(jié)構(gòu)的地震影響系數(shù)；對(duì)于主結(jié)構(gòu)，考慮了突出物對(duì)其地震力的影響。方法簡(jiǎn)便實(shí)用。
[關(guān)鍵詞]  底部剪力法 屋面突出物 主結(jié)構(gòu)

The horizontal seismic forces of tower-building coupled system are calculated by the seismic base shear method. The seismic-response factor for tower part atop tall building is presented, which is different from that of main-structure, and the effect of tower part on seismic force for main-structure is considered. This method is simple, practical, which could be used in aseismic design of such structure.
Keywords: tower buliding; coupled vibration; seismic; base-shear method
