About "GSTABL7 with STEDwin v.2"
Slope Stability Analysis System
GSTABL7 with STEDwin v 2.0, released in September 2001, is a completely new slope stability analysis software system which includes soil nails, geogrid reinforcements for any shape failure surface, piers/piles for slope stabilization, applied forces which can be applied to any soil boundary line, non-linear shear strength, curved failure envelopes, fiber reinforced soils, plots of stresses when a single failure surface is evaluated, and implementation of a General Limit Equilibrium method of slices, including Morgenstern-Price and Spencer's methods. We are now shipping 32-bit versions of the program which will run under Windows 95, 98, 2000, NT, Me, and XP.
The cost for a new GSTABL7 with STEDwin v.2 single-user site license with one hardware key in the USA is $1,275. Additional user licenses (with hardware keys) in the same office are $395 each. Click here to download more information on "GSTABL7 with STEDwin" v.2.
GSTABL7 was privately developed by Garry Gregory, P.E. The GSTABL7 program is not from Purdue University. All GSTABL7 software orders and requests for technical assistance are handled directly by Garry H. Gregory, P.E., GREGORY GEOTECHNICAL, 2001 West 44th Ave, Stillwater, OK 74074, USA, Phone: 405-747-8200, Fax: 405-747-8201.

GSTABL7 upgrade information: If you have an earlier version of GSTABL7 (v1.14. or v1.16) then you should upgrade now (use the order forms above). Technical support for these older versions of GSTABL7 has ended, as support was limited to a period of one year after the release of v.2
Demo version: Download a free demo of GSTABL7 with STEDwin v.2. Click here
STEDwin only - If you do not plan to purchase GSTABL7 v.2, then STEDwin 2.7 is also available separately for working with your current Purdue or PennDOT STABL programs. STEDwin is the smart editor for PCSTABL which runs under Win95, 98, NT, 2000, and XP. It allows on-screen data entry and modification similar to a spreadsheet. STEDwin itself performs no stability analysis but allows the user to concentrate on the engineering aspects of slope stability analysis while it takes care of writing the data files in the format expected by the slope stability analysis program.
STEDwin creates high quality graphics from the output files. The graphics can be printed in color or black and white to any printer supported by Windows, saved as .BMP files, or exported as AutoCAD compatible .DXF files. STEDwin supports the new PCSTABL7, PCSTABL6 (all versions released in 1999), PCSTABL4, STABL4M, PCSTABL5, STABL5M, STABL6H, and both PennDOT versions PASTABLE and PASTABLM. A new site license for STEDwin only is $300 and additional user licenses are only $50 for each additional user in the same office.

How to get Purdue University's PCSTABL program:
Purdue University announced a new version of STABL6 in March 1999. An update was released in January 2000). The new STABL6 includes geosynthetic reinforcements and soil nailing. Note that Purdue has also released a Windows version of STABL6, but only the DOS version is compatible with STEDwin. In November 2002, Purdue released their latest program, PCSTABL7, which is not the same as GSTABL7. STEDwin 2.80 is now fully compatible with Purdue's new PCSTABL7 program!

Free updates for STEDwin only (Not GSTABL7 with STEDwin):
I have developed a new 32-bit version that does not require write access to the STEDwin folder, and uses the Windows registry instead. If you have STEDwin version 2.70 to 2.79 (these are all 32-bit versions), then you may download a free update to version 2.80. Click here to go to the 32-bit download site. Then download the file Update_280_PCSTABL7.zip. The file is password protected, so you must email me and request the password before you can extract the new files into the directory/folder in which you originally installed STEDwin. Important: Do not download the 32-bit update unless you have one of the 32-bit versions of STEDwin listed above (v. 2.70 to 2.79)!
If you have 16-bit STEDwin (with a version number less than 2.70) you may download a free upgrade to version 2.64, the final release for the 16-bit version. Click here to go to the 16-bit STEDwin file download site.Then download the file updat264.exe and execute it, specifying the directory/folder in which you originally installed STEDwin. But, if you need to run STEDwin under Windows XP, then I strongly recommend upgrading to the new 32-bit version. In this new version, user settings are stored in the Windows "Registry" and the user no longer needs to have read/write access to the STEDwin program folder. (This is very helpful if your IT department has restricted the ability to save or change data files in program folders).
The cost to upgrade from the 16-bit version to the 32-bit version of STEDwin (v2.80) is $149 for the "site license" upgrade and $25 to upgrade each "additional user" license. To add more users, the cost is $50 for each additional user license.
(Please note that updates for STEDwin versions 3.0x (16-bit) and 3.5x (32-bit), which have been developed specifically for the new GSTABL7 v.2, are not available for download. Contact Garry Gregory for update information.)
