A Study on Dynamic Characters for RC Portal Frame under shaking Table Test by using HHT Approach


The adaptive data analysis method adopted in this paper consists of essential empirical mode decomposition (EEMD) associated with down-sampling process and the Hilbert– Huang transform (HHT). Precise results can be obtained from data containing white noise in nonlinear system than the data from the common method of Fourier transform, which is based on the… (More)
