[摘要] 通過對(duì)剪力墻結(jié)構(gòu)在倒三角分布荷載作用下的有害層間位移以及剪力墻墻肢邊緣處的豎向伸縮變形沿豎向分布規(guī)律的定量分析以及對(duì)工程實(shí)例的初步驗(yàn)證，指出如能大幅度放寬結(jié)構(gòu)層間位移角限值，則剪力墻結(jié)構(gòu)位移型阻尼器的有效位置主要在底部數(shù)層，既可以安裝常規(guī)的層間斜撐阻尼器，也可以把阻尼器沿豎向安裝在剪力墻邊緣構(gòu)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
