Fixed Issues in Autodesk Structural Bridge Design 2027.0
Issues Resolved In 2027.0
| Project / Structural Analysis |
| Suppressed unnecessary AS 5100.2 HLP exceeded by design load warnings when another variant of the same vehicle type governs in the extreme combination. |
| Resolved an issue where a generated PDF was not displayed in the Results View. |
| Fixed a Finite Element Previous Stage Load accumulation issue in staged construction analysis that could cause previous stage contributions to be underestimated or overestimated. |
| Fixed a crash caused by entering invalid numeric input (e.g. "0.0.4"). |
| Fixed an issue where Pedestrian Live Load was inactive on the CS 454 Highway Run Optimization tab when ALL Model 1 was selected. |
| Fixed the tree view auto-scrolling to top after renaming Design Sections or Design Beams. |
| Added validation to ensure user defined vehicle track and axle definitions start at zero. |
| Added detection of a wheel defined at both first track and first axle to user defined vehicle validation. |
| Fixed a crash when removing a user defined vehicle from the import list. |
| Resolved a missing grid and 'Show coordinates' checkbox in Plan view despite being selected in the General tab. |
| Design Beams |
| Fixed an internal error in Steel Composite beam analysis after changing span length. |
| Corrected Pre-tensioned beam shear resistance values for In-Situ infill per CS 455 in the presence of large axial tension. |
| Resolved an issue where the beam Analyze button was unresponsive when opening a single beam file from the File |
| Fixed a crash when creating a new beam of a different type from the single beam file currently open. |
| Fixed RC Beam analysis graphics not updating after opening Differential Temperature Analysis. |
| Fixed a crash when compression flange bracing is set explicitly (AASHTO LRFD). |
| Fixed a crash when changing the design code on the British Standards Shear Parameters form and closing the dialog. |
| Resolved an issue where the warning dialog could not be closed when analysing a Steel Composite beam during construction. |
| Fixed a crash when analysing a specific RC beam for the British Standards design code. |
| Corrected the Pre-Tensioned beam Shear Force resistance chart for nominal links where Vus,min was incorrectly set to zero (AS 5100:2017). |
| Fixed a missing 'Comb' dropdown on the Pre-Tensioned beam analysis form for beams with NZ group type transferred loading. |
| Resolved an issue where Code Edition was not displayed on the Home screen for some legacy beam files. |
| Disabled the incorrect SLS option for Longitudinal Shear analysis for Australian Pre-Tensioned beams. |
| Fixed a crash when running Differential Shrinkage analysis for a specific Australian beam. |
| Corrected the sign of the axial force (Nu) in the strain in reinforcement (εs) calculation for shear design when the force is in compression (AASHTO LRFD). |
| Fixed a crash on the Post-Tensioned beam Shear parameters form for AASHTO LRFD. |
| Fixed a crash when switching span for a Post-Tensioned beam (AASHTO LRFD 7+). |
| Design Sections |
| Corrected the Longitudinal Reinforcement calculation report per AASHTO LRFD Article 5.7.3.5 where the total was not the correct sum of its parts. |
| Fixed an issue where Initial Strains changes were not undone when clicking Cancel. |
| Fixed a crash when setting the description for a loadcase to empty. |
| Removed the incorrect Gamma f3 column from the Eurocode loadcase definition grid. |
| Fixed an issue where '1 bar 2 covers' reinforcement diameter was reset to default instead of retaining the value defined before clicking on the first face. |
| Fixed an issue where bundled tendon area was not correctly saved when exporting to JSON for automation. |
| Restored missing options on the British Standards Shear Parameters form that were unavailable in version 2026. |
| Corrected the resolved moment in Eurocode Design Section shear calculations with external tendons. |
| Corrected Axial Load values in the Moment Curvature report. |
| Corrected multiple issues in the Moment-Curvature report for US units including axial load display, curvature column formatting, limit state terminology, and section angle reset for multiple runs. |
| Resolved an 'Unable to access clipboard' error when pasting section loads with an empty description. |
