加强层结构和消能减震结构地震反应对比分析
|
摘要
以某超高层建筑为例,对比分析了加强层结构和带粘滞阻尼器的消能减震结构的地震时程反应,结果表明:消能减震结构的位移反应明显小于加强层结构,在地震作用下,消能减震结构能有效地减小结构的基底剪力,粘滞阻尼器消耗了大量输入到结构中的能量,有效地保护了主体结构。
Seismic time-history response is analyzed on structures with strengthened story and with viscous dampers of seismic energy dissipation structure in example of a super high-rise building.The study result shows that displacement response of structure with seismic energy dissipation is smaller than structure with strengthened story,the base shear forces in structure with viscous dampers is less than structure with strengthened story,seismic energy dissipation dissipates a large part of energy input by earthquake and protects main structure effectively.
