Development of Open Source Software for Use in Earthquake Engineering Applications: DARLA (Version 1.0)

Abstract

It is an important issue that earthquake characteristics and engineering intensity parameters can be determined quickly and practically to be used in earthquake engineering applications in the light of new developing technologies. Within this context, an increase is observed in software integration of engineering parameters. In this study, using Python software language, maximum acceleration (PGA), maximum velocity (PGV), and maximum displacement (PGD) values were calculated from time series records of strong ground motions of a certain earthquake; velocity-acceleration-displacement time series of records were produced; response spectra were visualized by comparing them with the design spectra defined in the Turkish Building Earthquake Code (TBDY-2018). Frequency contents of earthquake signals were also obtained (Fourier Amplitude-Frequency plots). It is aimed to provide ease of interpretation by visualizing the outputs obtained. With the help of the open-source software DARLA (ver1.0), which was developed within the scope of this study, it is intended to make a rapid assessment in the light of semi-automatically produced scientific data, in terms of earthquake engineering, specific to the region, from the moment the earthquake occurred.
