设计了三榀不同类型的钢框架结构模型,通过对模型的快速水平周期加载试验,进行了设置粘滞阻尼墙钢框架结构减振性能的比较和分析。对设置阻尼墙后钢框架结构的破坏形态、滞回特性、骨架曲线、阻尼力、抗剪刚度、耗能性能、等效阻尼比等进行了研究,对阻尼墙不同布置方式对上述各项性能的影响进行了分析,并对上述各项性能与加载频率、位移幅值的变化关系进行了探讨。结果表明,设置阻尼墙后,钢框架结构的耗能能力和阻尼均有显著提高,结构的抗剪刚度增加,结构的地震响应显著减小。设置阻尼墙钢框架结构的滞回特性与频率、位移幅值相关。阻尼墙不同布置方式对结构滞回特性的影响不明显。
Three different types of steel frame structure models were designed. Through the fast horizontal cyclic loading test of the model, the comparison and analysis of the damping performance of the steel frame structure with viscous damping wall were carried out. The damage form, hysteresis characteristic, skeleton curve, damping force, shear stiffness, energy dissipation performance and equivalent damping ratio of the steel frame structure after the damping wall are set are studied. The influence of different arrangement of damping wall on the above properties The influence of these factors is analyzed, and the relationship between the above properties and load frequency and displacement amplitude are discussed. The results show that the energy dissipation capacity and damping of the steel frame structure are significantly increased after the damping wall is set up, the shear stiffness of the structure increases, and the seismic response of the structure is significantly reduced. Setting the hysteresis characteristics of the damping wall steel frame structure is related to the frequency and displacement amplitude. The effect of different arrangement of damping wall on the structural hysteretic characteristics is not obvious.
