Description:

Purpose
This app can be used to generate elastic response spectra (acceleration, velocity, displacement) from accelerogram using Newmark's beta method.

Installation
Download the ElasticResponseSpectra.opx file, then drag-and-drop onto the Origin workspace. An icon will appear in the Apps gallery window.

Operation

  1. Activate a worksheet with XY columns or a graph with XY data plots.
  2. Click the icon in the Apps Gallery window to open the dialog. 
  3. Select a dataset as input and identify the unit of input accelerogram. 
  4. Specify Samping Interval of Record from input X data. Enter Maximum Period of Spectra and Spectra Interval Step for the spectra to analyze. 
  5. Specify beta and gamma values of Newmark's beta method. Specify Viscous Damping Ratio.
  6. Select quantities to output. You can change the units of output quantities.
  7. Click Preview to display the calculated spectra.
  8. Click OK to output data and create graph.
