This function can generate these elastic response spectra for an input accelerogram:
1. Elastic Pseudo Acceleration Spectrum (Spa),
2. Elastic Pseudo Velocity Spectrum (Spv),
3. Elastic Acceleration Spectrum (Sa),
4. Elastic Velocity Spectrum (Sv), and
5. Elastic Displacement Spectrum (Sd).
For this purpose, Newmark's method for linear systems was employed and the equation of motions was solved, numerically. This function is completely compatible with the 4th edition of the book "Dynamics of Structures" by A. K. Chopra.
