摘要

本文在前人工作的基础上提出了一种直接生成具有时-频非平稳特性的空间变异地震动的方法，即随机过程理论与相位差谱相结合的方法。此方法由于引入了相位差概念并结合己有的自功率谱、相干函数、视速度模型，从而使得生成具有时-频非平稳特性的空间变异地震动的过程更为直接和简便。最后通过几个合成示例说明了这种方法的有效性，可以用于结构多点输入地震反应分析。

Abstract

This paper presented a method to simulate the spatial varying ground motion with time-frequency non-stationarity, which combined the knowledge of stochastic process and phase-difference spectrum. This method with some empirical power spectrum density (PSD) models, coherency function models and the models of apparent velocity can make it easy and directly to be done that generates the spatial varying ground motions because of importing the concept of phase-difference. At last, some illustrations were presented to prove that this method aforementioned is effective and can be used in the response analyses of structure subjected to multiple input ground motion.
