提出了两种设置套管阻尼器的框架支撑结构。改变套管阻尼器的相对刚度、相对长度与屈服比等参数值以及套管阻尼器的布置方式,利用ETABS软件建立有限元模型,对框架支撑结构进行动力时程参数分析,提取结构的底部最大剪力和最大层间位移角作为结构地震响应的衡量标准,探究套管阻尼器的参数变化和布置数量对结构地震响应的影响规律,发现:对第一种结构形式,套管阻尼器的相对刚度、相对长度和屈服比宜取为0.4、0.5和0.2;对第二种结构形式,套管阻尼器的相对刚度、相对长度和屈服比宜取为0.6、0.5和0.4;并非各楼层都布置阻尼器可取得最佳的减震效果,对本文提出的两种设置套管阻尼器的工程应用形式而言,在底部四层设置套管阻尼器减震效果最好。
Two braced-frame structures with tube dampers are proposed. The relative stiffness, relative length and yield ratio of casing dampers and the arrangement of tube dampers are changed. The finite element model is established by the software ETABS, and the dynamic time history analysis of the braced-frame structures is carried out. The base shear and the maximum interlayer displacement angle of the structure are used to reflect the seismic response, and the influence of the parameter changes and the arrangement of the tube dampers on the structural seismic response is explored. It is found that the relative stiffness, relative length and yield ratio of tube dampers should be 0.4, 0.5 and 0.2, respectively, for the first structural form. For the second structural form, the relative stiffness, relative length and yield ratio of tube dampers should be 0.6, 0.5 and 0.4, respectively. It is not the best strategy to set dampers at every floor. For the two structural forms installing tube damper proposed in this paper, the best energy absorption effect is achieved by setting the tube dampers at the bottom four layers.
