The following table lists free TxDOT and FHWA engineering software to assist in highway
design. It provides an overview and minimum system requirements for each
BGS-TxDOT Bridge Geometry System
The TxDOT Bridge Geometry System(BSG) is used for bridge geometric design. The initial release of BGS, Version 8.1, was developed from the TxDOT Roadway Design System (RDS) Version 8.0 application by removing all non-bridge related RDS commands. The user may define, and display graphically, geometry points and curves, bridge alignments with templates, superelevation and widening, and bridge framing, with or without contours. The result of these changes to RDS is BGS, a "scaled down" implementation of TxDOT RDS that focuses on bridge geometric design.
An experienced RDS user will be able to begin using BGS immediately as BGS is used in the same way as RDS. The BGS and CAD plots are the same as RDS when applied to bridge geometric design.
BMCOL51- Beam-column analysis
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.

CAP18 - Bent Cap Analysis Program
A specialized structural analysis program using a discrete element model that produces envelopes of maximum bending and shear forces acting on bridge bent caps. Analytical results are for working stress and/or load factor design in accordance with the AASHTO LRFD Bridge Design Specifications or the AASHTO Standard Specifications for Highway Bridges. Users input live loads are automatically placed within users defined lanes to generate maximum forces at users specified points.
ConcreteWorks was developed at the Concrete Durability Center at the University of Texas as part of research funded by the Texas Department of Transportation (TxDOT). The system improves the constructability and durability of mass concrete bridge members and other structural members. Features include concrete mixture proportioning, thermal analysis, crack prediction, and chloride diffusion service life. It contains design modules for several mass concrete shapes, bridge decks types, precast concrete beams, and concrete pavements.

The user provides input data for loading conditions, structure geometry, and member sizes. The program outputs the member forces for use in either a working stress design or a load factor design in accordance with the AASHTO Standard Specifications for Highway Bridges, 17th Ed. for highway loadings, and AREMA 2006 in the case of E72 and E80 loadings.

released the original Windows version (7.0) in March 2007 and the second phase update (7.1) in July 2008. The HY-8 program has successfully operated on all current "flavors" of the Windows operating
HY-8 7.2 represents a "maintenance phase "of the FHWA's multi-phase culvert hydraulic software upgrade plan. In the future, the plan calls for using a pooled fund effort1 to fund and support incremental
upgrades and additions of features, based on available time, budget, and adoption of new hydraulic practices and techniques.

(http://www.wsdot.wa.gov/eesc/bridge/alternateroute/licenses.htm)
The TxDOT-customized version of PGSuper is versatile, user friendly, Windows-based software for the design, analysis, and load rating of multi-span precast-prestressed bridge beams/girders in accordance with the AASHTO LRFD Bridge Design Specifications (thru the 7th Edition, 2014, as modified by the 2015 Interim Revisions) and TxDOT design policies and guidelines. Properties of TxDOT standard I-girders (TxGirders), U beams, Slab beams, Decked Slab beams, Box beams and X-Beams and TxDOT design criteria are included in templates and libraries published by TxDOT on a server accessible via the Internet. Thus, the software is capable of periodically updating the installed templates and libraries with the most current versions published by TxDOT.
Custom defined beam shapes that fit within each family of girder types supported by PGSuper can also be added to a users installed copy of the templates, thereby extending the girder shapes that the user can design, analyze and load rate with the program.
The flexural design feature computes the required number and pattern of prestressing strands and the minimum required release and final concrete strengths. Specification checking evaluates girders for compliance with strength, serviceability and detailing criteria. Horizontal and vertical shear design, analysis and load rating is also facilitated.
A variety of results reporting is provided, including exhaustive and comprehensive reports, reports tailored to specific design or analysis features, fabricator optional design evaluation reports and a TxDOT Girder Schedule Report ("TxDOT CAD Output").
Certain functionality of this version of PGSuper has been enhanced over that of the previous release and most known issues/bugs present in the previous release are fixed in this release. For a list of these changes see the PGSuper support Information Document.
