摘要
本文分析了加强层和3种不同耗能减震层对框架-核心筒结构的减震效果,以顶点位移为目标对单个粘滞耗能减震层的最佳布置位置进行了研究,并分析了粘滞环带耗能构件对结构性能的影响。分析结果表明,耗能减震层比加强层更能有效地控制结构的地震反应;单个耗能减震层宜布置在结构的中部0.5H^0.6H处;粘滞环带耗能构件能有效减小结构的位移和内力。
Seismic effect of frame-tube structure with strengthened story and three different seismic energy-dissipation stories is analyzed. Optimal location of single viscous seismic energy-dissipation story is studied in the purpose of minimizing peak displacement. The influence of viscous energy-dissipation belts on structure performance is analyzed too. It is result that seismic energy-dissipation story can control seismic responses better than strengthened story. Single seismic energy-dissipation story should place in the middle part of structure. And viscous energy-dissipation belts can effectively reduce displacement and internal forces of structure.
