摘要/Abstract

摘要：

为进一步提高框架结构震后可修复性，降低建筑物地震残余位移，提出了增设自复位黏滞阻尼器加固方案。建立了自复位黏滞阻尼器的力学模型，利用一组黏滞阻尼器力学性能试验进行了验证，分析了3种初始压力下阻尼力特征，提出了单自由度框架安装黏滞阻尼器的抗震简化计算方法，并利用时程分析进行了验证。结果表明：在同一初始预压力下，随着加载频率的提高，屈服阻尼力、峰值阻尼力、耗能和等效阻尼比随之增大；在相同加载频率和位移幅值下，随着预压力的增大，屈服阻尼力、峰值阻尼力和能量耗散提高。时程分析表明随着结构周期增大，位移需求增大，自复位阻尼器方案框架底部剪力与普通阻尼器方案基本一致，普通阻尼器方案位移需求大于自复位阻尼器方案。自复位黏滞阻尼器可以用于高烈度区框架结构的抗震加固，相比于普通黏滞阻尼器具有较好的抗震性能。

Abstract:

In order to increase the post-earthquake repairability of frame structures and to reduce the earthquake residual displacement of buildings， the strengthening scheme of adding self-centering viscous dampers （SCVD） was proposed. The mechanical model of SCVD was established. The proposed model was validated through a suite of SCVD mechanical performance tests. The damper force characteristics of SCVD under three initial pressures were analyzed. The seismic resistant simplified calculation method for installation of viscous damper in single-degree-of-freedom frame structures was proposed and validated through history analysis. The results show that， under the same initial pressure， with the increasing of loading frequency， the yielding damping force， peak damping force， energy dissipation and effective damping ratio increased. Under the same loading frequency and displacement amplitude， with the increasing of initial pressure， the yielding damping force， peak damping force and energy dissipation increased. Compared with normal FVD mechanical property， the damping force of SCVD increased， the energy dissipation increased not much. The time history analysis of steel frame structure indicated that among the two damper layout scheme， the damper force of SCVD was bigger than that of fluidic viscous damper （FVD）， The frame displacement and residual displacement of FVD scheme were larger than that of SCVD scheme. The time history analysis showed that with the increasing of structure period， the displacement demand increased， the base shear of SCVD frame structure was nearly the same with FVD frame scheme， the displacement demand of FVD scheme was larger than that of SCVD scheme. The SCVD can be used for seismic strengthening of frame structures in high seismic intensity area， which has better aseismic performance compared with those of FVD.
