Abstract

Modeling and analyzing various issues in civil engineering, especially in the field of geotechnical earthquake engineering and earthquake engineering, has always been a complex, time-consuming and costly task. Accelerograms recorded by today's seismographs have a large amount of data due to the high accuracy of seismographs and their use in numerical methods and complex models leads to the formation of very large matrices and prolongs the analysis processing time. To reduce computational time, in this research, acceleration time-histories have been compressed using wavelet multi-resolution analysis method and the number of their data has been reduced. The original and compressed versions of accelerograms were used in five different seismic problems. The results demonstrated that one level of compression, which is equivalent to a 50% reduction in accelerograms data, reduced the duration of model analysis by 33% on average, while differential errors in the results are less than 5%.
