摘要
用底部剪力法计算带屋面突出物的高层建筑的水平地震力.对于屋面突出物,给出了有别于主结构的地震影响系数;对于主结构,考虑了突出物对其地震力的影响.方法简便实用.
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.
