| 摘 要： | 基于框剪结构采用钢结构直接加层后,结构的整体质量、刚度、周期等都会发生较大变化,对安装有软钢阻尼器和未设软钢阻尼器的加层钢结构运用有限元软件进行动力时程分析,分析表明：软钢阻尼器可以有效降低直接加层钢结构在罕遇地震下的反应,提高了结构的整体抗侧刚度,层间位移和层间剪力有显著的减小,较好地控制了钢结构直接加层产生的鞭梢效应现象,减震效果明显.

| Abstract: | Based on frame-shear wall structure,the overall quality,stiffness,cycle of the structure and so on will be greatly changed after adding layers directly with the steel structure.This paper uses a finite element software to make dynamic time-history analysis in plus mild steel damper layer steel structures,in which mild steel damper is installed or not installed.Analysis shows that mild steel damper can effectively reduce the response of added layer steel under the circumstance of rare earthquake,which improves the lateral stiffness of the whole structure,and significantly reduces the interlayer displacement and the interlayer shear,and this method properly controls the whiplash effect phenomenon produced by directly adding layers of steel structure,which make the damping effect obvious. |
