| 摘 要： | 本文提出了高层建筑结构的一种局部消能减震新体系.该体系既利用了上下部结构的动力反馈作用,又充分发挥了上部阻尼支撑的消能减震作用.分析发现:多遇地震下结构各层的层间剪力可以减小30%以上,下部结构层间位移可以减小30%～45%,楼层总位移也可以减小35%以上;罕遇地震作用下下部结构层间位移和楼层总位移也可减小20%左右.同时利用粘滞阻尼支撑将上部结构的层间位移控制在允许范围内. |
| 关 键 词： | 局部消能减震 粘滞阻尼 时程分析 有限元法 |

| Abstract: | In this paper,a new structure with local energy dissipation is put forward.Both dynamic interaction of upper and bottom structures and damper device are used to reduce seismic response.The researches indicate: Under frequently occurred earthquake,all story-shear can be reduced by more than 30 percent,story-displacement of bottom structure can be reduced by more than 30 percent and structural total displacement can be reduced by more than 35 percent.Under rarely occurred earthquake,story-displacement and structural total displacement of bottom structure can be reduced by about 20 percent,too. |
| Keywords: | local energy dissipation viscous damper time-history analysis finite element method |
