Flexure Sign(Effective Shear Depth)[Use Critical Shear Concurrent Bending Moment/User Positive Flexure/Use Negative Flexure/Use Pos and Neg Flexure]:This option allows the user to choose which flexure type should be used to compute the effective shear depth, as the value may differ under positive or negative bending. By selecting "Use Critical Shear Concurrent Bending Moment", the library component finds the critical shear force from all limit states and checks its concurrent bending moment, using either positive or negative flexure according to its sign. Choosing "Positive Flexure" or "Negative Flexure" forces the library object to compute the effective shear depth without considering any analysis results for the flexure sign. Finally, selecting "Use Pos and Neg Flexure" computes the effective shear depth for both flexures, and the critical one is used.
Select State Provisions[FDOT/PENNDOT…]: The code check component uses AASHTO 9th Edition standards as the default to calculate DC ratios and determine whether equations have passed or failed. Choosing a state specification does not impact these AASHTO-based computations, but rather serves as an additional requirement in OpenBrIM. The pass/fail status according to AASHTO and DOT standards are presented displayed in two separate summary tables, which will typically show similar resultsusually exhibit similar outcomes, with the DOT standards often being the more stringent. However, in some unique cases, a bridge component may fail AASHTO equations but pass due to overriding state specifications. Nonetheless, this is not a common scenario and DOT requirements are typically conservative.
