摘　　要：通过对黏弹性阻尼器力学性能的分析,得到了黏弹性阻尼器在任意时刻的恢复力公式,根据引入的三段变刚度模型,推导了变刚度黏弹性支撑结构体系的各段相对位移表达式,将此黏弹性支撑应用于高层钢结构体系,通过有限元软件对此体系进行时程分析,结果表明,装有黏弹性阻尼器的结构体系消能性能显著。The rebound formula of the viscoelastic damper at any time is received through the anlysis of mechanical properties of viscoelastic damper. Relative displacement formula of differ - rigidity viscoelastic brace is deduced by using the model of three - differ - rigidity available. As well as the braces are applied into the high - level steel structure system. The result of finite element of systerm with viscoelastic damper illustrate that the ability of dissipative energy is remarkable.
