摘要
本文阐述了为什么要研究复阻尼地震反应谱问题，并给出了复阻尼地震反应谱计算的精确方法．实例计算结果表明，复阻尼反应港与常用的粘性阻尼反应谱之间存在着相当大的差异．文中还简述了复阻尼系统运动方程的建立方法。
In this paper, why we want to study the problem of complex damping earthquake response spectra is recounted and how to exactly calculate such spectra is presented. A series of computational results demonstrate that there are considerable differences between the viscous damping spectrum commonly used and the corresponding one which is calculated by using the complex damping model. In this paper, also a procedure for formulating the equation of motion of complex damping systems is briefly related.
