| 摘 要： | 地震波频谱组成的研究主要是利用Fourier分析或小波理论，而地震波对建筑物动力反应的研究则是通过拟加速度反应谱来进行．现行分析方法的数值化过程必须通过计算机编程来实现，而采用常规的编程语言实现起来往往较为复杂．基于此，作者提出了基于MAT—LAB平台的分析方法，可以大大提高地震波动力特性分析的效率，便于分析结果的图形化输出，为工程结构抗震计算提供有益的参考．

| Abstract: | At present, the main theoretic method of earthquake wave spectral composition main are by means of Fourier or wavelet analysis. For studing of the dynamic response of buildings on the impact of earthquake waves, the pseudo-acceleration response spectrum will usually be introduced. The digital processing of above theoretic methods should be used of computting programme. It is difficult for the usuall computer programme to finish those ana- lytic processes. The article points out that the analyzing efficiency of dynamic characteristics of the earthquake wave will he improved greatly and the graphic result will be simply got on basis of Matlab language, the result of this article can be benefited for calculation of anti- earthquake of buildings＇ structure. |
