Abstract

 

In the first part of this paper a correction scheme, named as Band Limited Accelerogram Correction Scheme (BLACS) is presented for processing the records of analog accelerograph. In this part of the paper, comparison of this scheme is made with those of Lee and Trifunac, Erdik and Kubin and that of Khemici and Chiang. This is studied by comparing the response of the various schemes as well as their segments to white noise input which is assumed as uncorrected accelerogram. This comparison clearly brings out the advantages of using BLACS. A comparison is also done by affecting corrections on four uncorrected accelerograms using these achemes.The comparison is presented in a tabular form in frequency domain. A comparison is also presented by plotting response spectra of the corrected accelerograms obtained for the four earthquakes by BLACS with those of scheme of Lee and Trifunac. These results indicate that it is important to control the frequency contents of the data while processing as otherwise the final results may be substantially different.
