结构抗震实验中的批量数据处理软件开发及应用
|
摘要
结构抗震实验中通常会得到大量的实验数据,本文针对大数据量处理,利用Fortran 90与Graphic Lan-guage Editor(GLE)语言开发了数据分析软件,包括常规的FFT谱、加窗、滤波、功率谱、传递函数、相干函数、倒频谱、功率谱、相关以及场地谱比分析等,软件达到了以最少的输入参数得到最多的输出结果,尤其适合对批量数据进行分析和处理,并且同时完成计算分析和绘图功能.
Great amount of data will be obtained from once vibration measurement or seismic test,it is absolutely necessary to process the data with much more efficiency and accuracy.In this paper,the software pack is exploited.The program realized by the combination of Fortran 90 language and GLE(Graphic Language Editor) including following functions:FFT spectrum analysis,adding window functions,filtering analysis,power spectrum analysis,transfer function analysis,cross interfere function analysis,correlation function analysis as well as H/V(Microtremor spectral ratio of soil site).One of the advantages of the software is that data processing and plotting can be done by one operation,another is that a set of data can be processed and plotted by running the program one time.
