基于基础隔震理论提出框架剪力墙减震结构优化设计方法。针对1栋17层采用消能减震措施的框架-剪力墙结构,采用2种结构分析软件,选取2条实际地震波和1条人工模拟地震波分别进行线性与非线性时程分析。研究结果表明：该方法只需将黏滞阻尼器安装在结构底部数层,且没有布置抗震墙的轴线,即可取得较好的减震效果;将底部安装阻尼器的楼层称作隔震层,当隔震层基本周期与特征周期相等时减震效果最好;但基本周期不能由框架与抗震墙的总刚度推算,取总刚度与安装阻尼器的几榀框架刚度的均值来考虑抗震墙对隔震层刚度的贡献,可取得理想效果;该方法合理可靠,优化效果明显。

英文摘要：

An optimum energy dissipation design method of frame-shear wall structure was proposed based on the theory of base isolation. Two commercial structural analysis softwares and two sets of actual seismic records and one set of artificial acceleration time-history curve were adopted to conduct linear and nonlinear time-history analysis for a 17-floor frame shear wall structure equipped with energy dissipation devices respectively. The results show that the method considers the viscous dampers installed in the axis without shear wall and the bottom floors of the structure, and the number of floors can be determined by the site characteristic period. The bottom storey is called isolation layer, when the fundamental period of isolation layer is equal to the site characteristic period, the effects of vibration reduction are perfect. The fundamental period of isolation layer can＇t be calculated from the total rigidity of isolation layer frame and shear wall, but the contribution of shear wall shall also be considered. The method is reliable and rational with an effective optimum result.
