APPLICATION OF THE ALGORITHM FOR FILTERING ACCELEROGRAMS FROM NOISE USING THE WAVELET TRANSFORM IN THE STUDY OF SEISMIC LOADS
Real accelerograms are used as input data in the analysis of building structures. In the public domain, there are often only noisy instrumental recordings of accelerograms. Such accelerograms cannot be used directly in the deterministic analysis of building structures. Various broadband filters are used to adjust the instrumental recordings of accelerographs. This article discusses the possibility of using filters based on the wavelet transform. The technique of the algorithm of filtering from the noise of the source data is considered. The efficiency of this algorithm is shown by the example of the generated data. A comparative analysis of the energy criteria of the pulse and Arias was carried out as an efficiency of this algorithm for filtering a real accelerogram.
