高效数据分析方法及其在结构抗震实验中的应用
|
摘要
针对地震工程及结构抗震实验中得到的实验数据量大的特点,开发了高效率数据分析软件(Vi-ban2.40)。软件的功能包括 FFT 谱分析、加窗、滤波分析、功率谱分析、传递函数分析、相干函数分析、倒频谱分析、功率谱分析、相关分析以及场地谱比分析等。软件的开发原则是:尽量以最少的输入参数得到最多的输出结果。软件 Viban2.40的设计思想在于把 Fortran 语言和 GLE(Grapic LanguageEditor)绘图语言结合起来实现了分析和绘图一并完成,大大地提高了工作效率。软件 Viban2.40尤其适合对批量数据进行分析和处理,它的优点是在同时完成计算分析和绘图时,减少了出错的概率。它将为今后地震工程和工程振动试验工作者提供强有力的帮助。最后给出了一个应用实例,软件 Vi-ban2.40在香港高层建筑模型抗震实验数据分析中的应用。
Great amount of data is obtained from once vibration measurement or seismic test,it is absolutely necessa- ry to process the data with more efficiency and accuracy method.In this paper,the software pack(Viban 2.40)is exploited and it is a very practical and efficient software for vibration analysis.The program of Viban2.40 is real- ized by the combination of Fortran77 language and GLE(Graphic Language Editor),its functions are as follows: FFT spectrum analysis,adding window functions,filtering analysis,power spectrum analysis,transfer function analy- sis,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 batch data processing and plotting can be done efficiently,anoth- er is that a set of data can be processed and plotted simultaneously by running the program at a time.In general,vi- ban2.40 will play a very important role for data analysis and plotting in earthquake engineering and vibration engi- neering.
