ShakEdit
Pre & Postprocessor for SHAKE91
Postprocessor for SEISRISK III

Evaluation Version

SHAKE91 is the most commonly used computer program for the 1-D analysis of
dynamic soil response.  However, one of the limitations of SHAKE91 is the lack
of a user-friendly interface for creation of the input files, and for the
processing of the output data.  To this end, we have developed ShakEdit, a
Windows 3.1 based editor for SHAKE91.  In a typical application, ShakEdit is
used to create an input file for SHAKE91.  User-friendly screens are provided to
input the data for the different SHAKE91 options, and then to create the input
file.  After running SHAKE91 in a DOS window, ShakEdit is used to process the
output files.  The results can also be viewed graphically in ShakEdit, and the
graphics created can be saved/printed for inclusion in documents.

A quick tutorial is included as TUTORIAL.DOC.  This file is in Microsoft Word 97
format.  I recommend you to print it using a laser jet printer for better
results.  The files used in the tutorial are created during the installation
of the program.

Additional features of ShakEdit include:

* A number of equations used to estimate the maximum shear moduli, or Gmax,
  entered in Option 2.
* A number of Attenuation Relationships for peak horizontal acceleration and
  velocity with distance; and, for the pseudo acceleration or pseudo velocity
  response spectrum.
* Design spectra such as NEHRP, UBC and AASHTO.  These spectra and those from
  attenuation relationships can be plotted simultaneously with the spectra
  computed with SHAKE91.
* Computation of cyclic stress ratio using either a method based on: 1) the
  simplified equation by Seed & Idriss (1971); or 2) on equivalent uniform
  shear stress using the peak shear stress computed with SHAKE91.  Estimation
  of the cyclic stress ratio required to initiate liquefaction using standard
  penetration test results, and the CSR vs. N1,60 chart developed by Seed et 
  al. (1985).  Plot of the factor of safety against liquefaction curve.
* Two methods to compute settlement of saturated sands due to earthquake
  shaking: 1) Tokimatsu & Seed (1987) and 2) Ishihara & Yoshimine (1992).
* Calculation of permanent slope displacements due to earthquake shaking using
  the Newmark Method or the Makdisi & Seed Method.
* A postprocessor for SEISRISK III.  This computer program for seismic hazard
  estimation can be downloaded from:
  http://geohazards.cr.usgs.gov/eq/html/swmain.shtml
* A routine to retrieve the peak ground acceleration with 2%, 5%, or 10% 
  probability of exceedance in 50 years from the files of gridded points used
  to create the 1996 USGS National Seismic Hazard Maps.
* On-line help for most editing and graphing operations.


To install ShakEdit:

* Unzip the shkedd_1.zip, shkedd_2.zip, shkedd_3.zip and shkedd_4.zip files
  to a temporary directory in your computer (e.g. c:\windows\temp)
* In Windows choose File | Run from the Program Manager menu.
* In the dialog box that appears, type c:\windows\temp\install.exe
  Press Enter or click Ok to start the installation program.
* If your are using Windows 3.1 or 3.11 and have problems during the 
  installation, try using the INSTAL16.EXE program instead.
* A welcome screen appears.  Click on Next.
* A screen is displayed asking you to close any other Windows application.
* The license agreement under which ShakEdit is distributed is shown.  After
  reading it, click on Agree if you accept the terms.  Otherwise, click on
  Disagree to terminate installation of ShakEdit.
* A dialog box appears asking you for the directory path where you would like to
  install ShakEdit.  Click Ok to install everything to C:\SHAKEDIT, or type in
  any other path, or click on the icon on the right side of the text box to
  display a dialog form that will allow you to change the drive and/or
  directory path.
* After choosing a directory, click on Next.
* A dialog box appears asking you for the directory path to the Windows System
  subdirectory (e.g. C:\WINDOWS\SYSTEM).  If you are using Windows NT, this
  directory likely has a different name (e.g. c:\WINNT\SYSTEM32, etc.).
* A dialog box appears requesting you to choose a windows group for ShakEdit.
  After selecting a group, click on Next.
* If you want to create a shortcut to ShakEdit on your desktop, click on Yes.
  Otherwise, click on No.
* The installation program begins copying files from to the hard drive.
* A dialog box appears to inform you that a backup directory was created in
  the ShakEdit directory to save any *.DLL or *.VBX file that may have been
  updated during the installation.  Click on Ok.
* A dialog box appears indicating that the installation of ShakEdit is complete.
  ShakEdit is still under development.  I would appreciate your comments on how
  to improve, modify, or customize ShakEdit; and on any problems that you may
  encounter.  I continually update the software based on user's input, and
  periodically send free updates to registered users.  Click on Ok to complete
  installation of ShakEdit.
* You will be asked if you would like to reboot your computer to update any
  library file that may have been upgraded.  Click on Yes.
* I recommend that you install SHAKE91.EXE in the same directory where ShakEdit
  was installed.  Otherwise, you will need to modify the PIF file used to run
  SHAKE91 on a DOS window so that the path to SHAKE91.EXE is correct.

This evaluation version of the ShakEdit program can be distributed freely.
Two features of the full version have been disabled in this version.  The user
can not save the modifications to the input files, and the results can not be 
printed.

This program requires VBRUN300.DLL which is not included because of its size.
It is available from the Simtel.Net as vbrun300.zip at:

http://www.simtel.net/win3/dll/

It is also available from many on-line services and BBSs.

SHAKE91 or SEISRISK III are not included with ShakEdit.  

To buy the full version of ShakEdit, please visit our web site for more 
information on how to order with a credit card or by sending your payment in the
form of a money order or check in US dollars.  When you register you will 
receive a copy of the program including a User's Manual by mail to replace 
the evaluation version.
