Desarrollo de un software para procesamiento y corrección de registros, y generación de espectros de respuesta sísmica

Abstract

This technical project is based on the Development of a Software for Processing and Correction of Records, and Generation of Seismic Response Spectra. The software was developed through the Matlab computational tool, among its main functions we have the calculation with the use of matrices, the implementation of algorithms and the creation of user interfaces. The correction of the records began, first the baseline correction was carried out by means of the Berg and Housner method, which is a classic method that gives good results. The second correction that was made is the correction of the noise present in the signal through the different filters. Subsequently, the response spectra of acceleration, velocity and displacement were obtained based on methods in the time and frequency domain, whose methods were the Newmark, the Duhamel integral and the Fourier transform. Once the results of both the corrections and the response spectra of a record had been obtained, the verifications were carried out with the Prism program, from INHA University. Once the results were verified, we made a comparison between the three methods to know the similarity between them, it was verified that between the Newmark method and the Duhamel Integral there is greater similarity, than with respect to the Fourier transform method, due to that each method follows different paths to reach similar results.
