| 摘 要： | 本文利用有限元软件ABAQUS对设置和未设置新型椭圆形开口金属阻尼器的五层钢框架结构进行了罕遇地震作用下的弹塑性时程分析,研究该新型椭圆形开口金属阻尼器对多层框架结构的减震控制效果.分析结果表明,设置了椭圆形开口金属阻尼器的结构在地震作用下的反应明显小于未设置阻尼器的结构,且结构主体可以基本保持在弹性范围内工作,说明该新型椭圆形开口金属阻尼器的减震性能良好.

| Abstract: | liptic metal The nonlinear elastic-plastic time-history analysis of a five floors steel frame structure with the new el- damper and the same frame structure without damper under the infrequent earthquake were realized by ABAQUS program to study the vibration reducing performance of the new elliptic metal damper in muhistory frame structure. The numerical simulation results show that the new elliptic metal damper can greatly increase the additional damping level of the building structure and the structure of main body can keep working within the e- lastic range. It proves the vibration reducing performance of the new elliptic metal damper is good. |
