摘　　要：对适用于木结构加固的黏弹性阻尼器进行不同加载位移、加载频率和低周循环次数下的力学性能测试,研究设置2种阻尼胶的阻尼器在不同工况下的存储剪切模量、损耗剪切模量、损失系数、等效剪切刚度等。研究结果表明,随着加载位移、加载频率、循环次数的增加,设置2种阻尼胶的阻尼器损耗剪切模量、损失系数、等效剪切刚度均有所减小;总体而言,2号阻尼器耗能能力稳定且良好,较适用于抵抗多次循环荷载作用的建筑或局部结构中。In this paper,the mechanical properties of viscoelastic dampers which are suitable for wood structure reinforcement are tested under different loading displacement,loading frequency and low cycle times.The storage shear modulus,loss shear modulus,loss coefficient and equivalent shear stiffness of the damper with two damping adhesives under different working conditions are studied.The research results show that with the increase of loading displacement,loading frequency and cycle times,the loss shear modulus,loss coefficient and equivalent shear stiffness of the damper with two damping adhesives decrease.Overall,the energy dissipation capacity of No.2 damper is stable and good,which is suitable for buildings or local structures resistant to multiple cyclic loads.
