研究了大型非线性粘滞阻尼器的滞回力-变形反应以及用于数值模拟和抗震设计的反应模型。研究了600kN非线性粘滞阻尼器在正弦载荷作用下的力-变形响应。在表征测试中使用了广泛的幅度和频率。提出了一种用于大型非线性粘滞阻尼器的力-变形响应的非线性Maxwell模型，用于非线性响应历史分析。本文还提出了一个非线性粘滞阻尼器串联的力-变形响应的等效线性模型，该阻尼器具有连接到建筑结构所需的弹性支撑和连接部件。等效线性模型使结构构件的弹性柔度对阻尼器-支撑构件反应的影响在抗震设计中得以考虑。0.6缩尺三层结构设置非线性粘滞阻尼器的试验结果验证了当量线性模型的预测精度。还分析了结构构件的弹性弹性(如支撑和连接)对设置非线性粘滞阻尼器的建筑结构有效刚度和阻尼比的影响。
Studied are the hysteretic force–deformation response of large-scale nonlinear viscous dampers and model of the response for use in numerical simulations and seismic design. The force–deformation response of nonlinear viscous dampers with a force capacity of 600 kN are characterized under sinusoidal loading. A wide range of amplitudes and frequencies are used in the characterization tests. Anonlinear Maxwellmodel is presented for modeling the force–deformation response of large-scale nonlinear viscous dampers for use in nonlinear response history analyses. This paper also presents an equivalent linear model for the force–deformation response of a nonlinear viscous damper in-series with the elastic bracing and connection components needed to connect the damper to a building structure. The equivalent linear model enables the effects of the elastic flexibility of structural components on the response of the damper-brace component to be considered in seismic design. Results from tests on a 0.6-scale three-story structure with nonlinear viscous dampers validated the predictive accuracy of the equivalent linear model. Also evaluated are the effects of the elastic flexibility of structural components (e.g., bracing and connection) on the effective stiffness and damping ratio of a building structure with nonlinear viscous dampers.
