Fixed Issues in Autodesk Structural Bridge Design 2026.0
Issues Resolved In 2026.0 Hotfix 2
| Project / Structural Analysis |
| Fixed a math error given by "GlobalFuncsMath.LongIntAtOrBelow" in CS 454 load optimization calculations and improved performance by up to 5x. |
| Resolved a memory limitation issue that caused a core overflow error and prevented model calculation. |
| Design Beams |
| Removed torsional parameters from US steel composite beam design data. |
| Fixed an issue where Pre-Tensioned beam sections became corrupt when automating temperature or shrinkage and creep analysis. |
| Fixed an issue where transverse reinforcement required for torsion was underestimated according to AS 5100.5:2017. |
Issues Resolved In 2026.0 Hotfix 1
| Project / Structural Analysis |
| Resolved an issue with the display of US LRFD design code version in the 'Create From Template' form. |
| Fixed an internal error when creating a new concrete material for a US LRFD 9 beam. |
| Fixed an issue with user defined vehicle zero position wheel check. |
| Design Beams |
| Revised US LRFD Pre-Tensioned Beam tensile stress limits. |
| Design Sections |
| Fixed analysis of specific Australian curved pier section. The fix is in the calculated area for torsion and may now give a different value for non-box sections. |
| Fixed a general issue when starting US LRFD 9 design section analysis. |
| Fixed an internal error when generating an interaction surface for a US LRFD design section. |
Issues Resolved In 2026.0
| Project / Structural Analysis |
| Fixed an issue that prevented the update of the InfraWorks bridge model from Structural Bridge Design model for a steel girder bridge change. |
| Resolved an issue that prevented C# Automation of Structural Bridge Design 2025 from post-processing results. |
| Temperature loads can now be added to a dead load compilation. |
| Fixed the opening of project files that contain a corrupted carriageway definition. |
| Fixed the processing of Eurocode ULS Accidental loads in Interaction Surface analysis, both manually and via automation. |
| Blocked assignment of Post-Tensioned Beams to a Line Beam. |
| Fixed Robot Structural Analysis engine not installed error, versions 2024 and 2025, which blocked RSA model creation. |
| Design Beams |
| Fixed incorrect decompression height calculations and results formula for Eurocode Pre-Tensioned Beam analysis. |
| Applied EN 1992-1-1 3.1.7(3) Note regarding reduction factor: "If the width of the compression zone decreases in the direction of the extreme compression fibre, the value η fcd should be reduced by 10%." |
| Design Sections |
| Accepted change following the edit of section element coordinates without leaving the grid. |
| Resolved section library selector duplicate names. |
