摘要

以某超高层建筑为例,对带加强层结构和带粘滞耗能减震层结构的地震反应进行了对比分析,分析结果表明:(1)带粘滞耗能减震层结构的地震反应明显小于带加强层结构的地震反应;(2)在地震作用下,带粘滞耗能减震层结构比带加强层结构的内力分布更为均匀,结构内力无明显突变现象;(3)带粘滞耗能减震层结构不会产生应力集中现象。
Seismic responses are analyzed on structure with strengthened story and with viscous seismic energy dissipation story in example of a super high-rise building.The study results show that:(1) Seismic responses of structure with viscous seismic energy dissipation story are smaller than the structure with strengthened story;(2)The internal forces distribution in structure with viscous seismic energy dissipation story are more uniform than the structure with strengthened story;(3)There is no stress concentration phenomenon in structure with viscous seismic energy dissipation story.
