• Technical Note 87 – Bridge Parameters XML Version Conversion Issue – BrDR version 7.7.1 corrects an issue in the XML version conversion process where bridge parameter information on the Description (cont’d) tab of the Bridge Description window was not imported when bringing bridges into the software. This behavior occurred only during XML import and did not affect database migration. The update ensures that all parameter information on this tab is now imported consistently during XML version conversion. See Technical Note 87 – Bridge Parameters XML Version Conversion for more information.

• Technical Note 85 – Gusset Plate Partial Shear Planes – BrDR version 7.7 updates the terminology used for gusset plate partial shear planes to improve clarity and consistency between the input tab and F1 Help. The shear plane directions are now labeled as Smaller Angle Partial Plane and Larger Angle Partial Plane to reduce misinterpretation. See Technical Note 85 – Gusset Plate Partial Shear Planes for more information.
• Technical Note 86 – Cross-frame Axial Rigidity Coefficients – Default Behavior – BrDR version 7.6 introduces input fields for axial rigidity coefficients in the Diaphragm Definitions window. For 3D LRFD/LRFR analysis with the 10th Edition of the LRFD Bridge Design Specifications, if no values are entered, BrDR now applies default coefficients as per Article 4.6.3.3.4c for single-angle and tee-section cross-frame members. This update may affect models created with earlier versions. See Technical Note 86 – Cross-frame Axial Rigidity Coefficients – Default Behavior for more information.
