[摘要] 通过对剪力墙结构在倒三角分布荷载作用下的有害层间位移以及剪力墙墙肢边缘处的竖向伸缩变形沿竖向分布规律的定量分析以及对工程实例的初步验证，指出如能大幅度放宽结构层间位移角限值，则剪力墙结构位移型阻尼器的有效位置主要在底部数层，既可以安装常规的层间斜撑阻尼器，也可以把阻尼器沿竖向安装在剪力墙边缘构件上。

Abstract: By means of quantitative analysis along the vertical dispersion of harmful displacement of floors and stretching deformations at the edge of wall of shear wall structures in the inverted triangle distributed load and preliminary validation of engineering instance, it pointed out that if the limit of story drift angle be significantly relaxed, the effective positions of displacement-type dampers in shear wall structures would be at the bottom of several storys, both conventional bracing dampers also dampers along vertical on the edge of the component of shear wall can be installed.
Keywords: shear wall structure; harmful story drift; stretching deformation at the edge of wall; displacement-type damper
