Shear Stud Code Check (AASHTO) [SIG]
Shear Stud Code Check (AASHTO) [SIG]
General
Girder: Girder for code check
Code Check Template: The code check template is utilized to extract global parameters, results from finite element analysis, and limit states employed in the design process.
Pitch/Fatigue Control Station Method[User Input/Check Nth Station]: The method applied to the control stations is defined by this parameter.
Check every Nth station: The start and end stations of the shear stud group define the boundaries (the first and last elements) of the checking station list. Within these boundaries, the distance is discretized according to the specified distance (N). Additionally, if a girder bearing station falls within these two endpoints, it is also automatically included in the final list.
Pitch/Fatigue Control Stations: This parameter allows the user to manually define the exact station locations where the Pitch/Fatigue checks for shear studs will be performed. This input is only utilized when the 'Control Station Method' parameter is set to 'User Input'.
Res. Case To Find Pos. Neg. Flexure Zone: Specify the result extraction case used to determine the critical longitudinal regions positive, negative, and intermediate moment zones required for the Strength Limit State checks, as per AASHTO LRFD 6.10.10.4.
Straight/Curved[Straight Bridge/Curved Bridge]: This parameter defines the bridge type.
Ignored Insertion Points for Span Positioning: Usually, no selection is needed in this section as the span definitions are automatically determined by the object using the connected insertion points, which represent the bearing locations. However, if some of the connected insertion points are not bearings and instead represent temporary supports, they should be selected and marked as ignored.
PDF Name (Export): This parameter allows the name of the code check document to be modified when saving it as a PDF. When renaming the file, special attention must be given to the text characters on the linked page, as certain characters may interfere with parametric equations and lead to unexpected results.
Deck Reinforcement
Input Data Preference [Override Deck Rebar/Use Deck Rebar]: For deck rebar to be used in shear stud code checks, users are provided with two options. The code checks can either be conducted using the modeled deck rebar or with new rebar definitions.
If the input data preference is defined with the option 'Override Deck Rebar,' the parameters listed below can be used to define the rebars for code checks. Otherwise, if the input data preference is defined with the option 'Use Deck Rebar,' the parameters below will not be applicable.
Lumped Top Reinforcement Area within the Effective Width: This parameter can be used to specify the lumped reinforcement area within the effective width when overriding deck rebar.
Distance from the Centerline of Top Bars to the Top of the Deck: This parameter can be used to define the distance from the centerline of the top reinforcement bars to the top of the deck.
Lumped Bottom Reinforcement Area within the Effective Width: This parameter can be used to specify the lumped reinforcement area within the effective width for the bottom deck rebar.
Distance from the Centerline of Bottom Bars to the Bottom of the Deck: This parameter can be used to define the distance from the centerline of the bottom reinforcement bars to the bottom of the deck.
Deck Rebar Material: This parameter can be used to specify the material used for the deck rebars.
Concrete Creep Adjustment Factor: This parameter can be used to define the adjustment factor for concrete creep in calculations.
Overrides
Override Effective Deck Width[Yes/No]: The Override Effective Deck Width parameter provides the option to manually specify the effective deck width instead of relying on the automatically calculated value. When set to “YES,” it allows engineers to enter a user-defined deck width that may better represent the actual structural condition, such as when the composite action is partial or the geometry is irregular. When left as “NO,” the system computes the value automatically.
Effective Deck Width: The Effective Deck Width parameter defines the deck width used in composite section calculations when the override option is enabled.
