Included in the text output are geometric data and reports that may be imported into various MicroStation design files to include angles, dimensions, elevations, etc. In the bridge plans as needed to accurately fabricate and place the various bridge elements during construction as well as determine bid item quantities during preparation of the PS&E package. BGS Version 8.1 (a.k.a.

V8.1.7, released June 2007) was developed from TxDOT Roadway Design System (RDS) Version 8.0 by removing all non-bridge related RDS commands. The result of these changes was a 'scaled down' implementation of RDS that focuses on bridge geometric design. In BGS v8.1 the user could define, and display graphically, geometry points and curves, bridge alignments with templates, superelevations and widenings, and bridge framing, with or without contours, but code supporting RDS functionality strictly employed in roadway design was removed from the RDS source code to yield BGS. BGS v8.1.7.2 was deployed in November 2011 as a technical release to address OS issues with v8.1.7. By November 2011 work was underway on BGS v9.0 building upon the v8.1.7.2 source code. By January 14, 2014 more than 195 distinct changes had been made to BGS v8.1.7.2 including bug fixes, enhancements and modifications to yield development version 9.0.3. In addition to these functional changes, the source code for the BGS component bgs1.exe_which performs all geometric and plotting calculations and output reports_was migrated from the Intel compiler v10 (integrated with VisualStudio 2008) to v11 (integrated with VisualStudio 2013) and a number of modifications were made to the interface program component bgs.exe.

The resulting BGS v9.1.5 was released in January 2016 but had to be recalled due to a bug that blocked bearing seat elevations from being included in the formal output listing for certain framing options. The bug-fixed version, BGS v9.1.6 was released in February 2016. The current draft of the BGS v9.1 User Guide is over 360 pages long. Due to file size and for other reasons it is not deployed directly to the end user's machine but is rather stored on TxDOT_s FTP server. Users can access the guide via a link to it installed in the Bridge Geometry System (BGS) program group.

This decoupling of the BGS User Guide from the packaging of the software allows for revision on an as-needed basis throughout the life of BGS v9.1. This BGS User Guide, like the old RDS User Manual, should provide all the information that the user will need to run the software. An experienced RDS user will be able to begin using BGS immediately. The BGS input data, output computations, reports and CAD plots are the same as produced by RDS when applied to bridge geometric design, notwithstanding the effects on output of numerous bug fixes and enhancements made to BGS since its initial release.

See the, linked in the same manner as the, for instructions on how to report bugs and wishes about program functionality or get technical support. Technical support is available to all TxDOT BGS users and any consultant BGS users designing bridges for TxDOT. Processor: See recommended minimum for OS.

Generalized beam-column discrete element model to analyze simple and continuous beam subjected to concentrated, uniform, uniformly varying, and non-uniformly varying static and movable traverse loads. The program considers the effect of axial load on stiffness. It models spring supports, rotational spring restraints, and concentrated applied torques, It analyzes a beam-column of up to 999 discrete increments of user defined length.

Flexural stiffness may be prismatic, uniformly varying, or non-uniformly varing. Processor: Pentium 133Mhz Memory: 32mb Free Disk Space: 200kb Operating System: Win 32-Bit Version: 5.2.3 Date: Size: 1.0mb PGSuper is now part of the BridgeLink application framework. BridgeLink is an integrated suite of bridge engineering software. BridgeLink links together several different bridge engineering software tools into one convenient and easy to use platform. The software tools included in BridgeLink are BEToolbox, PGSplice, PGSuper, TOGA, and XBRate. BridgeLink has been collaboratively developed and maintained by the Washington State Department of Transportation (WSDOT) and the Texas Department of Transportation (TxDOT) under the Alternate Route Project initiated and managed by WSDOT. () This TxDOT-customized version of PGSuper is versatile, user friendly, Windows-based software for the design, analysis, and load rating of multi-span precast-prestressed concrete bridge beams/girders in accordance with the AASHTO LRFD Bridge Design Specifications (thru the 8th Edition, 2017) and by TxDOT design policies and guidelines.
