UTILITY SOFTWARE FOR DATA PROCESSING:
USDP (Utility Software for Data Processing) is a user-friendly computer program that can be used for strong ground-motion data processing and spectral calculations.
The program was developed by the METU-Earthquake Engineering Research Center team under the financial grant provided by the Technical Research Council of Turkey for the "Turkish National Strong Ground-Motion Data" project (Award No. 105G016). USDP uses public-open Fortran sources that have been developed by Dr. David M. Boore (U.S. Geological Survey, Menlo Park CA) for data processing and elastic spectral computations including the Fourier amplitude spectrum.
- Strong motion data processing by various filtering and baseline adjustment techniques
- Linear spectral analysis (Spectral displacement, Pseudo-spectral acceleration and velocity, absolute acceleration and velocity spectra) for different damping values
- Fourier spectral analysis
- Constant strength, ductility and base-shear coefficient nonlinear spectral analysis for different non-degrading and stiffness-degrading as well as stiffness and strength degrading hysteretic models
