Early Access Releases (After August 2025)

  1. A new feature has been added that enables users to rename PDF files of Code Check reports. (All Workflow)

  2. Pier Column: Add rigid lines at the midpoints of section-ext edges for uniform load distribution. (All Workflow)

  3. Shear Stud code check fix: For tub girder demands, the required number of shear studs per AASHTO LRFD Section 6.10.10.4.2 was correct, but OpenBrIM was only counting one flange (half of the studs provided) in the pass/fail check, even though the demand was for the entire box girder. (Steel Tub Girder Workflow)

  4. Revisit bottom node generation of the column object. Fixes the issue of not generating a 6×6 stiffness matrix when the connected pile’s finite generation is disabled. (All Workflow)

  5. Introduce an “Apply Multiple Presence Factor to Lane Load” input to the library object. (All Workflow)

  6. The "DGN Additional Properties" objects are now available within the workflow. (All Workflow)

  7. A new feature has been added that enables users to rename PDF files of Substructure Code Check reports for State Provisions. (All Workflow)

  8. Improvements for limit state object: In some of the code check objects, the unfactored force computation logic was using result cases directly without verifying the applied factors, since the goal was to obtain unfactored forces. However, issues arose when users entered a factor of 0 and assigned it to a result case. To resolve this, if the factor is set to 0, the unfactored force list for the corresponding limit state will now exclude that result case. (All Workflow)

  9. Steel Tub Girder Load Rating: The DC1 torsional moment used in the shear demand calculation previously applied factored strength loads; it has now been updated to use unfactored loads. The torsional moment analysis results have been added to the analysis results table to track computations. (Steel Tub Girder Workflow)

  10. Steel I Girder Load Rating / Steel Tub Girder Load Rating: The rating factor equation for the tension flanges under negative flexure previously used fbuBot_DC. It now uses fbuTop_DC, since under negative flexure the top flange is in tension. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  11. The distortion of the skewed support line on the 3D deck has been resolved. (All Workflow)

  12. Camber Diagram: Previously, the camber report sometimes used displacement values from nearby deck nodes (because the function retrieved results by coordinates), but it now only takes values from the relevant girder nodes. (Steel I Girder Workflow / Steel Tub Girder Workflow/Precast I Girder Workflow)

  13. The rebar calculation method has been added to all concrete objects in the precast I-girder workflow. (Precast I Girder Workflow)

  14. Section and material inputs have been added as read-only fields in the Quantities tab. (All Workflow)

  15. Gross Volume, Cutout Volume (Girder Intersections), and Net (In-Place) Volume have been added to the end diaphragm section in the Quantities tab. (All Workflow)

  16. Pier cap sections are now independent of the elevation grade in the 3D view. (All Workflow)

  17. DGN Additional Properties now support clearer data handling with defined value types (Text or Number), improved numeric entry options (including parametric values or references to other cells). Each numeric entry can be linked to a unit of measure, and a read-only final value is displayed in the specified unit. (All Workflow)

  18. A back wall was added to the GDOT abutment. (All Workflow)

  19. Shear Stud Code Check: A new 'AASHTO Edition' input has been added to the Shear Stud Code Check Template. You can now explicitly select whether to use the 9th Edition or the 10th Edition for shear connector design calculations. Selecting an edition will automatically activate the corresponding specification logic and requirements. (Steel I Girder Workflow)

  20. Shear Stud Code Check: An 'Overrides' tab has been introduced to the Shear Stud Code Check object (similar to the Girder object). This enhancement allows you to manually override the effective width value used in the section calculation, giving you greater control over your design parameters. (Steel I Girder Workflow)

  21. Shear Stud Code Check: A new 'Configuration' input has been added to the Shear Stud object. This allows you to define your shear studs as either Regularly Spaced or Clustered. This enhancement supports the specialized design equations introduced in the AASHTO 10th Edition for clustered shear connector arrangements. (Steel I Girder Workflow)

  22. Steel I Girder Code Check : When AASHTO Appendix A6 is active, calculations in the detailed reports now fully display the relevant parameters. To ensure continuity of information, the Yield Moment and Plastic Moment sections have been moved out of the primary 'Flexure' grouping, allowing them to remain visible even when Appendix A6 governs. Consistent with this, the standard AASHTO Article 6.10 capacity checks are now correctly removed from the detailed report for active A6 cases. (Steel I Girder Workflow)

  23. Steel I Girder Code Check : A critical change has been made in the Summary Report: the single 'IS APPENDIX A6 APPLICABLE' column has been split into two distinct flags: 'IS APPENDIX A6 APPLICABLE (POS)' and 'IS APPENDIX A6 APPLICABLE (NEG)' for clearer applicability based on the flexure sign. This separation resolves a previous reporting gap by ensuring that the corresponding AASHTO Article 6.10 Demand/Capacity (D/C) ratios are reactivated and displayed if Appendix A6 is not applicable for a given moment sign. Previously, these 6.10 D/C ratios were incorrectly suppressed even when A6 could not be utilized. (Steel I Girder Workflow)

  24. Steel I Girder Code Check / Steel Tub Girder Code Check / Steel I Girder Load Rating / Steel Tub Girder Load Rating: The calculation for Dcp​ (depth of the web in compression at the plastic moment - in positive flexure) has been corrected. Based on the user input in the template object, the contribution of deck rebars is now properly ignored in the Dcp​ equation when they are excluded from the main plastic moment calculation. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  25. Steel I Girder Code Check / Steel Tub Girder Code Check / Steel I Girder Load Rating / Steel Tub Girder Load Rating: Additionally, a new input for overriding the span length has been added. You can now also view the calculated span length and effective deck width values as read-only in the Overrides tab on Girder Codechecks and Girder Load Ratings. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  26. Steel I Girder Code Check: The Appendix A6 section of the report has been updated to clearly explain the origin and meaning of the Dcp and Dc parameters used in the calculations. Additionally, the formula for Dcp (depth of the web in compression at the plastic moment in positive flexure) has been corrected to properly exclude the contribution of deck reinforcement when rebars are not included in the main plastic moment calculation, based on the user’s template settings. (Steel I Girder Workflow)

  27. Steel I Girder Code Check / Steel Tub Girder Code Check: The fatigue stress range (Δf) was previously calculated using the formula abs(Min Stress) + Max Stress. This has been updated to abs(Max Stress − Min Stress), which more accurately represents the maximum absolute range between the extreme stress values. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  28. Shear Stud Code Check: Fixed section properties (Inertia, d_topofsteel) used in the additional shear connector calculations at pier locations, which are detailed in the Special Requirement for Points of Permanent Load Contraflexure document section. (Steel I Girder Workflow)

  29. Shear Stud Code Check: A new input, 'Include Interior Support Stations', has been added. This parameter controls whether the interior support stations are automatically added to the list of stations defined manually by the user for Pitch/Fatigue checks. This is particularly helpful since it can be numerically challenging to manually input the exact girder support stations, especially at skewed piers. (Steel I Girder Workflow)

  30. Shear Stud Code Check: In conjunction with the general provisions set by the 'AASHTO Edition [9th/10th Edition]' input, the design report for shear studs in steel tub girders now incorporates several key updates, including corrections to fundamental shear calculations. The Pitch table has been enhanced to explicitly display both the minimum (pmin​) and maximum (pmax​) allowable pitch. Critically, the resultant fatigue shear range (Vsr​) calculation for box girders (Article 6.11.10) has been redefined: it is now the vectorial sum of the longitudinal fatigue shear range (Vfat​) and the Torsional Fatigue Shear Range (frange​), replacing the previous sum involving the transverse (radial) shear range (Ffat​). Consequently, Ffat​ calculations are removed, and detailed torsional shear range calculations are presented in new tables. This shift required concurrent adjustments to address previous shortcomings in shear calculations: while the Vfat​ calculation is now explicitly divided by two (in line with AASHTO 6.11.10's requirement to use one-half the composite section's moment of inertia), the frange​ calculation remains as the original single-web shear value, correcting a prior omission where the flexural shear component was not properly divided. (Steel Tub Girder Workflow)

  31. Steel Tub Girder Code Check / Shear Stud Code Check: In previous versions, the enclosed area value shown in the detailed report (which correctly follows the Steel Bridge Design Handbook) was not consistently used in the background calculations, leading to a slight difference of about 2% in the computed results. This inconsistency has been resolved. The enclosed area value in the detailed report now fully aligns with the value used in all calculations. (Steel Tub Girder Workflow)

  32. Pile: The 3D misalignment issue of the single pile constructed beneath the column has been resolved. (All Workflow)

  33. Stress Summary Table: The Stress Summary Report object has been significantly enhanced; it now collects minimum and maximum load factors as user inputs for load cases, and based on this data, two new key components—a comprehensive Stress Range Graph and a detailed Tension Zone Table—have been implemented. Furthermore, Unfactored Moment Graphs have been added to display the moments for individual load cases, along with a graph illustrating the combined total of all load cases. (Steel I Girder Workflow)

  34. Stress Summary Table: An input has been added under the Overrides input tab to allow users to override the effective concrete deck width, which is used to compute composite section properties (such as section inertia and section modulus). (Steel I Girder Workflow)

  35. Girder / Deck : A new mesh algorithm has been introduced to better support complex meshing requirements in the superstructure, such as the modeling and analysis of transfer and kicker girders. This enhancement adds a new Mesh Algorithm input under the Deck object, allowing users to select from various meshing strategies based on geometry complexity. The newly supported algorithms include options such as Frontal-Delaunay, Frontal-Delaunay for Quads, Packing of Parallelograms, Quasi-structured Quad, MeshAdapt, and Automatic, in addition to the previously available GridMesh method. These algorithms significantly improve mesh quality and flexibility, particularly for irregular and skewed bridge geometries. Furthermore, the Girder object has been updated with dedicated input fields for Transfer Girder and Connecting Girder parameters, providing enhanced control over mesh generation and alignment in complex superstructure configurations. (All Workflow)

  36. Bolted Gusset Plate Code Check: Fixed an issue concerning the 'Plate Shear Plane Area' calculation. Previously, the area calculation incorrectly utilized the distance between the exterior bolt and the plate edge. The logic has been updated to correctly use the full plate width to determine the shear plane area.. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  37. Bolted Field Splice Code Check : The computation logic for do​ (transverse stiffener spacing), which is used in the Girder Shear Capacity calculation within the Splice Plate Code Check report, has been updated. Previously, do​ considered the stiffener spacings two before and two after the splice plate. The logic is now revised to correctly use the distance between the immediate stiffener before and the immediate stiffener after the splice plate. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  38. Pay Item : Payitem properties are now automatically added to DGN exports and assigned to 3D objects. (All Workflow)

  39. GDOT Abutment : The GDOT Abutment 3D issue occurring under skewed and curved alignment conditions has been resolved. (All Workflow)

  40. Bolted Field Splice : The splice bolt quantities have been corrected. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  41. Camber Diagram : The Camber Diagram display logic has been updated to ensure consistency with the expected boundary conditions at supports. Displacement values, which previously reflected movement due to flexible bearing stiffness, are now adjusted using linear interpolation between bearing locations. This method ensures the displacement is zero at all support points, providing a clear diagram for field construction. (Steel I Girder Workflow / Steel Tub Girder Workflow / Precast I Girder Workflow)

  42. Camber Diagram : The display logic for the camber diagram table has been simplified. The 'Position' label, which previously showed station differences, has been replaced with 'Length along Girder Line'. This ensures the table now clearly reflects the actual length along the girder. (Steel I Girder Workflow / Steel Tub Girder Workflow / Precast I Girder Workflow)

  43. Concrete Girder Code Check : It is now possible to assign combinations to the Concrete Girder Code Check for time-dependent runs. Deck stresses are now displayed in the summary report. (All-Concrete workflows)

  44. Pier Cap Construction : Pier cap construction has been improved. It is now possible to perform weight-only construction. (All Workflow)

  45. PennDOT Integral Abutment : The tapered wingwall was excluded from the input parameters. (Steel I Girder Workflow)

  46. PennDOT Integral Abutment : The 3D modeling issues at the backwall–wingwall connection were resolved. (Steel I Girder Workflow)

  47. PennDOT Integral Abutment : Additional chamfer-related errors were corrected. (Steel I Girder Workflow)

  48. Tub Girder Stress Summary Table" object has been added to the workflow under the Report tab. (Steel Tub Girder Workflow)

  49. FEA Bearing now supports compression-only, tension-only, and nonlinear curve support inputs. Additionally, a gap input has been added to allow free support movement up to a specified displacement limit. (All Workflow)

  50. Shear Stud Code Check : Previously, when using a user-defined pitch/fatigue station list, interior support stations needed to be manually included. The 'Include Interior Support Station [YES/NO]' input has been removed, and interior support stations are now automatically appended to the user-defined list. This change ensures that checks required by AASHTO Article 6.10.10.3, which requires additional shear connectors at interior supports, run consistently and without manual user intervention. (Steel I Girder Workflow / Steel Tub Girder Workflow)

  51. Camber Diagram : A new input option, 'Support-Normalized Displacement[Enabled/Disabled],' has been introduced to control how displacement results are displayed at support locations. Previously, the normalization logic (zeroing displacements at supports and adjusting intermediate stations via linear interpolation) was applied automatically. (Steel I Girder Workflow / Steel Tub Girder Workflow / Precast I Girder Workflow)

  52. Pier Column Code Check : The AASHTO LRFD Article 5.6.3.3 Minimum Reinforcement Check in the Column Design Report has been significantly updated for accuracy and clarity. Previously, the check utilized the governing factored moment Mu across all directions but only compared it against the Y-direction resistance Mr The new, correct methodology separately evaluates the minimum reinforcement requirement for each principal direction (Z and Y), checking the corresponding Mu against the appropriate directional Mr for its respective axis. This results in the DC ratio now being displayed individually for both the Z and Y directions in the detailed report. Furthermore, to provide full transparency on the capacity value used in this check, the Moment Capacity calculation is now explicitly included immediately following the minimum reinforcement equation, clearly showing how the term Mr (Factored Flexural Resistance) is derived for that specific direction. (All Workflow)

  53. Precast I Girder : The Squared Ends [YES/NO] input has been introduced under the visual settings. When set to YES, this input ensures that skewed girder ends, tendons, and reinforcement are generated without being affected by the skew angle, allowing for simplified modeling and detailing. (Precast I Girder Workflow)

  54. Bearing Forces: Fixed an issue in Bearing Forces result extraction where results were not returned for bearings not connected to the substructure. (All Workflow)

  55. Concrete Deck : Resolved an issue where, only when the deck girder layout was straight, the haunch points corresponding to the girder were incorrectly being affected by the cross slope. The haunch points now maintain the correct horizontal alignment in this specific configuration. (Steel I Girder Workflow / Precast I Girder Workflow / Concrete Box Girder Workflow)

  56. Concrete Deck : Corrected an issue where the input thickness values for the left and right deck overhangs were not being reflected accurately in the model, as they were incorrectly being affected by the cross slope. The overhang thickness now accurately matches the input, independent of the cross slope. (Steel I Girder Workflow / Precast I Girder Workflow / Concrete Box Girder Workflow)

  57. Cross Frame Code Check : Added the Top Strut Unbraced Length [Full Length/Half Length] input to allow users to set the top strut unbraced length to half the original length. (Steel I Girder Workflow / Steel Tub Girder Workflow / Precast I Girder Workflow)

  58. Hinge Property: The moment-curvature report object can be directly assigned to the hinge object to define spring properties that depend on axial force. (All Workflow)

  59. Static Pushover Graph: Adds a summary-level report object that presents the Nonlinear Static Pushover results (Base Reaction–Displacement), enabling a comprehensive comparison of Demand/Capacity (D/C) ratios with Response Spectrum Analysis (RSA) case displacements. (All Workflow)

  60. Bearing Forces: The process for transforming bearing reactions into nodal forces has been improved. Previously, two-node spring generation was skipped only when no girder layout was assigned to the pier cap. Now, each insertion point is checked individually, and two-node springs are generated only where girders are present. This ensures more accurate and consistent spring generation. (All Workflow)

  61. Plan and Elevation CADD : The vertical offset behavior for substructure notations has been corrected. The previous behavior of sequentially offsetting the notations downward for adjacent substructures has been removed. The specified vertical offset value now applies consistently to the notations of all substructure objects. (All Workflow)

  62. Plan and Elevation CADD : Girders are now correctly drawn when a span gap is present. (All Workflow)

  63. Cross Frame Code Check : Added the Bottom Strut Unbraced Length [Full Length/Half Length] input to allow users to set the bottom strut unbraced length to half the original length. (Steel I Girder Workflow / Steel Tub Girder Workflow / Precast I Girder Workflow)

  64. Concrete Deck : A new input, 'Overhang Bottom Flat[YES/NO], has been introduced. This input is only activated when the 'Taper' input is set to NO. Its purpose is to explicitly flatten the bottom surface of the concrete deck overhangs. Otherwise the overhang bottom aligns with the existing cross slope angle. (All Workflow)

  65. Cantilever Abutment : The Cantilever Abutment object has been added. (All Workflow)

  66. Plan and Elevation CADD : The Cantilever Abutment drawings have been added to the plan and elevation CAD object. (All Workflow)

  67. Abutment Section Database : The abutment sections have been added to the section database. (All Workflow)

  68. Pier Column Code Check : ß_d Parameter Correction, We corrected the calculation of the ß_d parameter for column slenderness. It now correctly uses the maximum factored permanent load moment instead of the unfactored moment, leading to more accurate Interaction Diagram D/C Ratios. (All Workflow)

  69. Pier Column Code Check : Cracking Control 's' Fix, The 's' parameter in the AASHTO 5.6.7-1 cracking equation is now accurately determined along the main axes (Y and Z) for rotated sections (e.g., Front Side, Left Side). (All Workflow)

  70. Pier Column : Circular-Parabolic Section is now available for non-prismatic columns with circular-parabolic variations through a new section type option. Users can now choose between Straight-Tapered, which is the existing functionality, and Circular-Parabolic section types. Furthermore, the incorrect mirroring of the asymmetric section's Finite Element (FE) model was fixed to ensure it matches the 3D geometry. (All Workflow)

  71. Stem Wall : New input Reference [Support Line/Column(s)] added. The stem wall can now be placed under selected column(s). The finite element connection between the stem wall and the footing was corrected/resolved. The necessary parameters for meshing the footing are now correctly exported along the rigid lines created beneath the stem wall. (Steel I Girder Workflow)
