To verify the effectiveness of the subspace algorithm, a 2- dimensional frame structure with 20 DOF is provided to illustrate the identification process.application/pdf89841 bytesapplication/pdfzh-TW國立臺灣大學工程科學及海洋工程學系暨研究所Subspace algorithmAccelerance Frequency Response Function (AFRF)Modal modelPhysical modelreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/3971/1/882611E002008.pdf
