Autodesk Structural Bridge Design 2024.1.2

Project / Structural Analysis
- Fixed an issue that prevented rail traffic load optimization for Eurocodes.
- Added a more rigorous valid roadway (carriageway) check.
- Corrected an issue for CS 454 load optimization for Load Model 2, to ensure lane loads do not overlap.
- Corrected an issue for CS 454 load optimization for Load Model 2, to avoid loading the remaining area.
- Refined the transverse placing of Load Model 1 vehicles in CS 454 load optimization.
- Fixed removal of UDL displaced by CS 454 HB vehicle or accidental loading.
- Resolved an issue in the application of the impact factor for CS 454 Fire Truck loading.
- Refined CS 454 HB and non-uniform convoy loading position.
- Fixed a regression for load optimization to BD 86/01.
- Fixed a freezing issue for the Tabular Results custom filter save and open dialog.
- Fixed alignment of UDL with HO loading for NZTA rating optimization.
Design Beams
- Resolved an issue for beam cross section display at positions where there is a section step change.
- Fixed a distribution factor calculation access violation error for RC and PO beams.
Design Sections
- Incorrect stress-strain curve display on Service Parameters form close.
- Fixed incorrect torsional parameters for a box girder that are used in web crushing shear and torsion calculations to AS5100.5 Clause 8.2.1.2, 8.2.4.4 and 8.2.4.5.

Convert SST to JSON via automation
- Added ability to convert binary model file (containing design sections and/or design beams) SST to JSON via automation.
