| 摘 要： | 探讨了超塑性Zn—22Al合金阻尼器的减震性能。以12层钢框架结构为算例,采用通用有限元分析软件AN-SYS,选用3条地震波,对结构有无安装超塑性Zn—22Al合金阻尼器板进行了动力时程反应分析。通过对比在罕遇地震下结构的层间位移角与层间剪力,得出这种阻尼器具有较好的减震性能,可用于结构减震。

| Abstract: | The damping performance of superplastic Zn--22A1 damper is studied in the paper. Taking a twelve -floor steel frame as example , this paper applies finite element software ANSYS10.0 to the frame whether has damper or not and conducts dynamic time-history analysis by putting three earthquake waves. Finally, by the comparison of the inter-story displacement and the inter-story shear, we can conclude that the damper has a better damping performance and can apply to structure earthquake mitigation. |
