Abstract
A thorough understanding of an earthquake is very important to provide a descriptive knowledge and in the same time as a prescriptive knowledge for the future development. In particular, it is essential for site selection and structural design development of nuclear reactor and other critical facilities. Ground motion acceleration time history is an important raw information to understand the earthquake and specific geological condition of where the data is recorded. This paper presented the development of strong-motion analysis code, called Winston-BATAN, which able to interpret ground motion time history. The analysis scope of the code including the ground motion parameters such as peak ground acceleration, several additional seismic intensity parameters, strong motion duration, its frequency content via Fast Fourier Transformation and response spectra analysis. Being developed based on an open source Python programming language, Winston-BATAN is flexible for exploratory study to exploit the ground motion time history and easily improve to accommodate additional features. This code able to read input from PEER NGA type file or a simple time and acceleration data type of ground motion. Analysis results of Winston-BATAN shows a very good agreement compare to the results from the standard tools Seismosignal® 2018 Software, in addition flexibility of this code, in particular, to explore the response spectra from the ground motion time history is demonstrated.
Highlights
A thorough understanding of a natural event which might cause a huge impact, such as earthquake, is very important
The resulted calculations were than compared to commercial software of Seismosignal® which developed by Seismosoft as a standard tools in ground motion analysis [6]
These parameters can be used as a measure of the frequency content of the ground motion including the use of peak ground velocity (PGV)/peak ground acceleration (PGA) and peak ground displacement (PGD)/PGV in estimating the respective corner periods at which the constant acceleration plateau and the constant displacement plateau begins
Summary
A thorough understanding of a natural event which might cause a huge impact, such as earthquake, is very important This understanding can be used descriptively to explained past events, and in the same time become an accumulated prescriptive knowledge for future development. Construction of critical infrastructure, such as nuclear reactor, required a comprehensive knowledge of past and predicted future earthquake is very important This knowledge is needed to choose the appropriate site for the construction and the structural and safety design of the nuclear reactor. This paper’s objective is to elaborate the development of strong-motion analysis code which based on open source Python 3 coding language called Winston-BATAN It is Winston-Batan: A Seismological Ground-Motion Analysis Code, The resulted calculations were than compared to commercial software of Seismosignal® which developed by Seismosoft as a standard tools in ground motion analysis [6]
