RREELLEEAASSEE NNO OTTEESS for BRASS GIRDER STD Version 6 4 October 2014 General The BRASS incident tracking system can be found at www wydot brass com Users without an account on the incident tracking system can request an account by clicking on the Open a Technical Support Account link button and e mailing the address or calling the phone number listed A username and password will be created and sent to the user All BRASS technical support questions should be logged in this system Program Maintenance The following issues were addressed for this release The incident number is listed in parentheses after each issue if applicable Maintenance Corrected the section dimensions and properties for the W24X76 shape in the BRASS sections library The previous dimension and properties did not match any edition of the AISC Manual of Steel Construction Therefore the dimension and properties in the library were edited to match the 7th Edition The 8th Edition also list this shape but with different dimensions and properties so this shape was added to the library as W24X76B 703 Implemented the integration with AASHTOWare Bridge 6 6 Updated the export from AASHTOWare Bridge to implement a control option to ignore LFD shear rating for steel beams by exporting the shear capacity reduction phi factor as a large value Bug Fixes Corrected the calculation of the bending reduction factor Rb so the web2. slenderness check of AASHTO 10 48 4 1 is bypassed when Rb is forced to be calculated using Equation 10 103b as specified in AASHTO 10 53 1 3 689 BRASS GIRDER STD V6 4 1 Release Notes Corrected an error with applying the vehicle scale factor to a floorbeam analysis executed from AASHTOWare Bridge Rating This can be seen by differences in the As Requested versus Detailed rating results in earlier versions The scale factor is now applied to the vehicles in the virtual stringer analysis 717 Corrected an error with the shear capacity of a steel girder For some points the shear capacity was being limited to that of the end panel 730 Added a calculation to establish the end panel length in a steel girder If a transverse stiffener schedule is input for a span then the first or last range in the transverse stiffener schedule will be used as applicable to establish the end panel Otherwise 5 of the span length will be used The shear capacity will be limited to C Vp if the point of interest lies within the end panel 730 Due to size limitations within the BRASS GIRDER STD Graphical User Interface no new command parameters could be added Program Verification The critical rating factors obtained for numerous bridges using Version 6 4 were compared to Version 6 3 The data files used in this regression testing came from the following sources BRASS GIRDER STD example problems 15 Pre
