摘要
在地震作用下,框支剪力墙结构随着转换层设置位置的不同,表现出不同的地震反
应;同时转换层上、下部刚度比对结构的抗震性能有重要影响。此外,在罕遇地震作用
下,框支剪力墙结构将进入弹塑性阶段,结构的弹塑性地震反应与线性反应也有很大不
同。
本文首先阐述高位转换层的结构特征、研究现状和应用情况,同时回顾与总结高层
建筑抗震设计理论的发展。然后采用 SATWE 对不同高位转换结构进行弹性时程分析,
研究转换层设置位置对框支剪力墙结构动力特性的影响;并改变转换层上、下部刚度比
进行计算,总结刚度比的变化对结构抗震性能的影响。
最后,本文采用能力谱法对一高位转换层结构在大震下抗倒塌能力进行验算,结果
表明,按现有的设计方法对结构进行配筋,并加强构造处理,高位转换结构在大震下为
不会倒塌的。
对算例结果的分析表明,随着转换层位置的提高,对层位移和层间位移角曲线有明
显影响,而控制转换层上、下等效刚度比并不能完全有效地控制层位移和层间位移角的
突变。而后,针对高位转换层对结构的不利影响,通过分析、对比和研究,以转换层上、
下结构等效侧向刚度比和层间位移角比为目标,提出对结构实施“双控”的概念,克服
当前采用单一目标的不足。同时,结合工程应用特点,给出了参数的取值范围,可供理
论研究、工程设计与应用参考。

摘要
ABSTRACT
The frame-supported shear wall structures with transfer floors located at different height
responses differently to ground motion. The seismic behavior of frame-supported shear wall
structures is also dependent on the ratio of stiffness. Furthermore, the structures e
into elastic-plastic phase under major earthquake and the elastic-plastic seismic responses of
the structures show great paring with elastic seismic responses.
The paper first expounds the structural characteristics 、Present situation of research and
application of transfer floor, and retrospect and summary of the development of seismic
design theory of tall buildings. The elastic time historey analysis of structures with transfer
stories located at different height is plished and the results are discussed. By changing
the ratio of stiffness, this paper sums up the effect of ratio of stiffness on seismic behavior of
frame-supported shear wall structure.
In the last, a pushover analysis of seismic performance in strong earthquake pleted
and the seismic ability and failure of the structure is investigated.
The analytical results indicate that the displacement and rotation in any two adjacent
stories change greatly along w
