摘要
系统研究了AR和ARMA时间序列方法生成给定加速度功率谱人工地震波的新方法,根据相应理论编制了程序,并生成了人工地震加速度时程曲线,然后用生成的人工地震波进行结构动力时程分析,与实际地震波分析的结果进行了对比,计算结果表明,本文用于合成人工地震波的方法是可行的,生成的人工波可以用于实际结构的地震反应分析。
A new method of AR and ARMA models to simulate earthquake wave with given acceleration power spectrum is generated by the method and corresponding computer program is developed in this paper. Results of numerical examples indicate that the artificial earthquake wave generated by the method is applicable to practical structure dynamic time history analysis
