Concrete Pier Cap Code Check [STG]
General
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.
Pier Cap: Pier cap or bent for code check. The selected object is only used for extracting the results of an analysis and performing demand computation. Capacity computation will rely on the reinforcement information and section collected in this section.
Code Check Loc(Dist from Right End): The distance from the right end (when looking upstream along the PGL) of the pier cap, where the code checks will be performed, can be specified using this parameter.
Design Section w Rebars(or Tendons)[Override Section/Section from 3D]: Override Section: If the override section is selected, then the section entered by the user to override the section(w/ longitudinal rebars) parameter will be used for code check purposes. This is typically done if the user wants to try different rebar or section alternatives within one design run and doesn't want to change the active pier cap data. Section from 3D: If the section from 3D is selected, then the code check object will automatically create a section at code check station with longitudinal rebars from the pier cap. Make sure that all required reinforcement data is entered into the pier cap.
Override Section: Select a section that contains longitudinal rebars. This section will be used for capacity computations at the proposed station entered in the 'Code Check Loc(Dist from Right End)' parameter.
Shear Reinforcement Data[User Input/From 3D]: If 3D is selected, make sure that all required reinforcement data is entered into the pier cap.
Below parameters are active If Shear Reinforcement Data is selected as User Input
Shear Reinforcement Profile: This parameter can be used to select the shear reinforcement profile.
Shear Reinforcement Material: This parameter can be used to select the shear reinforcement material.
Spacing of the Shear Reinforcement: This parameter can be used to specify the spacing of the shear reinforcement.
Number of Legs of Shear Reinforcement: This parameter can be used to indicate the number of legs of the shear reinforcement.
Check For[Flexure Only/All]: The rigid beam connection between the pier and the pier cap may lead to high shear forces in a station located within the pier region during finite element analysis. As a result, evaluating shear in these areas may result in incorrect predictions of failure. To mitigate this issue, users can opt to examine flexure only in these regions.
Detailed Report 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.
State Provisions PDF Name (Export): When 'State Provisions' is selected, this parameter allows customization of the generated code check report's name. As with the 'Detailed Report PDF Name' input parameter, careful attention must be paid to the use of illegal characters.
Design Parameters
