摘要: 在介绍黏滞阻尼器减震框-剪结构抗震设计方法的基础上,提出按阻尼力与楼层剪力呈正比的方式分配阻尼系数的方法,并采用渐进法的思想实现对结构所需附加阻尼比更为精确的计算。结合工程实例,对已装及未装黏滞阻尼器的框架-剪力墙模型进行建模分析,就结构相关性和经济性进行对比,进一步考察黏滞阻尼器的减震效果,为工程设计提供参考。Abstract: Based on the introduction of seismic design of frame-shear wall structure with viscous dampers, this paper put forward the method of distributing damping coefficients according to the direct proportion of damping force and floor shear.The nibbling method was adopted to realize more accurate calculation of additional damping ratio needed by the structure.Combining examples of building design, the frame-shear wall structures with or without viscous dampers were modeled and analyzed to compare their structural performance and economic effects;which were further studied the effect of viscous dampers.
