摘要
本文以 92 1台湾地震的 30组近断层加速度时程为样本 ,研究了他们的周期(频率 )和幅值的随机特性 ,主要内容包括峰值加速度PGA、特征时刻与持时、幅值概率密度谱、幅值包线、周期频度谱以及穿零率函数。提出了二次峰点法求包线的方法 ,并建立了相应的数学模型
In this paper,the acceleration time history of 30 near fault stations triggerd by September 21 ,1999 Taiwan earthquake is taken as sample to study the random characteristic of periods (frequencies) and amplitudes The main content includes : peak ground acceleration (PGA),characteristic time and duration,amplitude probability-density spectra, amplitude envelope ,period-frequency spectra and crossing-zero rate functions A double peak point method is presented to find the envelope,and the corresponding mathematical model is established
