BrDR 7.9 RADBUG Enhancements and Maintenance Tasks in the Works

September 24, 2026

The BrDR Task Force prioritized and approved the following RADBUG enhancements and maintenance tasks for the BrDR 7.9 release.

List of RADBUG enhancements selected for the 7.9 release:

• BSSD-1605 Harped Strands Improvements

This enhancement improves the harped strand capabilities in BrDR and the Prestress Girder Design Tool.  This includes allowing 2 harp locations and providing hold down force calculations.

 

• BSSD-1833 Analyze Local Web Yielding and Web Crippling for Steel Beam Ends

This enhancement evaluates LRFD Appendix D6.5 Web Local Yielding and Crippling for steel girder bearing locations for LRFD and LRFR analyses.

 

• BSSD-3610 Evaluation for Shear per MBE 6A.5.8

This enhancement implements, in LFR, the average shear reinforcement area per unit length when multiple shear reinforcement patterns cross the shear failure plane as described in MBE 6A.5.8 for concrete beams (reinforced, prestressed and post-tensioned).

 

• BSSD-3805 ARC Tool: Report Bridges that Failed to Analyze

This enhancement creates a report of bridges that failed during the analysis run.  Additional details will be added to the report when available in the analysis output.

 

• BSSD-4012 Steel Design Tool: Provide Steel Weight for each Design and Review Option

This enhancement updates the Steel Plate Grider Design Tool to report steel weight for both the generated option using Design Input and modified option using Design Review.

 

• BSSD-4342 Specify Separate “Default Analysis Settings Template” for BrR and BrD

This enhancement allows users to set default templates for BrR and BrD separately.

 

• BSSD-4736 Default Tabular Results Display Format to “Single Rating Level Per Row”

This enhancement allows users to default whether the Tabular Results window displays one rating level per row or multiple rating levels per row.

 

List of larger maintenance tasks selected for the 7.9 release:

• BSSD-1612 Option Using Curved Guide Spec Impact Factors

This maintenance task allows users to choose if the Standard Specifications impact factors or the 2003 Curved Guide Specifications impact factors are used in a 3D LFR analysis.

 

• BSSD-1643 Report Culvert Load Combination Legend

This maintenance task is to consistently report the vehicle legend in the AASHTO LRFD/LRFR/LFR Culvert Engine specification check articles.

 

• BSSD-1853 Mark Not Computed Rating Factor as NC

This maintenance task implements reporting “NC” which means “Not computed” in rating articles for scenarios when the rating factor is not computed due to various reasons.  The rating factor will continue to be reported as 99.0 when the live load is zero.

 

• BSSD-5407 Implement LRFD 6.10.3.4.2 for 2 & 3 Girder Systems

This maintenance task implements LRFD 6.10.3.4.2 for 2 & 3 steel girder systems in an LRFD design review for the 10^th Edition LRFD Specifications.
