摘要
本文给出了一种物理意义明确的计算一般阻尼线性系统随机地震响应的方法．对于系统内部无调谐作用的情况，得到了在数学格式上与比例阻尼系统完全相同的系统响应的简化计算方法。
In this paper, a method with clearly physical meaning for stochastic response of non-proportionally damped linear system, based on random vibration theory,are proposed. For the system in which the tunning effect does not exist,a simplified formula is obtained, which is identical with that for proportionally damped linear system in mathematical form.
