ProShake changes/fixes since version 1.00 (in reverse chronological order)

Version 1.12 (February 2007)

1. Added feature to analyze multiple input data files, in sequence, in the Solution Manager.
2. ProShake is now available with a Parallel or USB port hradware key.
3. Added a feature, available from the "Utilities" menu of the main window, for user specified period or frequency for response spectra computation.
4. Fixed problem that caused the Input Manager to display an incorrect damping curve for the first layer when an existing input data file is opened.

Version 1.11 (September 2001)

1. Added feature to extract header information from PEER STRONG MOTION DATABASE RECORD motion files to the Convert Earthquake File Utility.

Version 1.10 (June 1999)

1. Added feature to plot multiple response spectra and a target spectrum in the Input Manager.
2. Added feature to compute and plot mean and mean +/- s spectra in Input Manager.
3. Users can now select Metric or US Customary units to be used in the report for tabular data.
4. Additional ground motion scalar parameters have been added.
5. Added ability to compute mean and mean +/- s values of scalar ground motion parameters assuming normal and/or lognormal distributions.

Version 1.10 (November 1998)

1. Fixed incorrect labeling in stress plots and CSR in Output Manager.
2. CSR changed to decimal format in Output Manager.

Version 1.10 (September 1998)

1. Added Transfer Function computation and plotting features to Output Manager.
2. Fixed problems in the response spectrum plots in Output Manager with Logarithmic axes.
3. Fixed problem in copying large graphics (large number of data points in the graph) to Report.
4. Fixed problem in CSR computations.
5. Fixed problem in computing Fourier spectrum in Input Manager when the number of Fourier term is 16384 (maximum allowed in ProShake).
