【摘要】：对比研究不同的人工地震加速度时程的计算方法,发现不同方法之间的主要差异在于初始时程的获得方式,包括采用与设计响应谱相近的真实地震过程和基于通过响应谱与功率谱密度间近似关系的方法。基于后一种方法,开发人工地震加速度时程计算程序。采用计算实例进行人工加速度时程计算,得到的人工时程具有良好的形态和统计特征参数;人工时程响应谱与设计谱具有良好的相容性。
[Abstract]:Comparing and studying the different calculation methods of artificial seismic acceleration time history, it is found that the main difference among different methods lies in the way of obtaining the initial time history. It includes the real earthquake process which is similar to the designed response spectrum and the method based on the approximate relation between the pass response spectrum and the power spectral density. Based on the latter method, the artificial earthquake acceleration time history calculation program is developed. The artificial acceleration time history is calculated with an example, and the artificial time history has good morphological and statistical characteristic parameters, and the artificial time history response spectrum has good compatibility with the design spectrum.
