工程结构采用粘弹性阻尼器的反应谱设计理论研究

STUDY ON SEISMIC DESIGN THEORY OF RESPONSE SPECTRUM OF ENGINEERING STRUCTURES USING VISCOELASTIC DAMPERS

根据先前研究成果并结合抗震规范,给出了安装粘弹性阻尼器后结构的地震影响系数的修正计算公式:探讨规范反应谱分析阻尼结构的方法,分析了阻尼变化对位移、速度和加速度反应谱的影响,建立考虑阻尼影响的三种反应谱之间的关系,最后给出了粘弹性消能结构的减震设计方法。

Based on the conclusions of the recent research, and combined with the seismic standard, the modified formula for seismic coefficients of engineering structures using viscoelastic dampers is given. The analytic method of damper-added structures using the response specturm standard is discussed. The effect of varying the damping ratio of an engineering structure on its response spectrums of displacement, velocity and acceleration is explored. The relations among the response spectrums of displacement, velocity and acceleration are established. The seismic design method for engineering structures with viscoelastic dampers is put forward at last.
