🔬 Revisiting Code Check Templates with a Special Focus on Columns
Under the "Design Criteria" section, you can navigate to the "Code Check Templates" subsection. Once there, you will find a spreadsheet that displays a collection of imported code check templates (as shown in Figure 1d).
...
One important aspect of the code check template is the source of the analysis result, which determines how the ultimate capacity of the column is calculated. To modify the analysis result source for the selected code check template, you can click on the button located under the "Analysis Result Source" cell. If multiple analysis sources are selected, the envelope of those selections will be considered.
Clicking on this button will open a menu or dialog box where you can make the desired selection for the analysis result source. The available options may include different analysis methods or sources, such as tributary analysis, finite element analysis (SAFE, ETABS), or AECBOLTGlobal. Figure 1g provides a summarized visual representation of the steps involved in selecting the analysis result resource for a column code check template.
Selecting the appropriate analysis result source is crucial in accurately assessing the column's capacity and ensuring compliance with design standards.
...
These two cells, "Changes After Last Code Check" and "Code Check Timestamp," offer valuable insights into the code check process, allowing users to track and review the alterations made to the model and refer to the timestamp for the most recent code check operation.

Column Schedule
The column schedule displays information such as column size, rebar dataprovides a tabular representation of essential details related to the columns, including their sizes, rebar information, and the ultimate axial force acting on the each column at each every floor. This information is presented schedule is displayed in the drawing space, typically in a table format in the drawing space, as shown depicted in Figure 2.
By default, the ultimate force analysis source for the columns is set to tributary analysis. However, it is also possible to set specify a different analysis source by referring to the section Column Scheduleanalysis source for determining the ultimate forces of the columns. To make changes to the analysis source or explore further options related to the column schedule, refer to the Column Schedule section.

Figure 3
When there is a discontinuity column transfer in the column design line, a red point is created on the corresponding cell in the spreadsheet. By moving the cursor over this red point, additional information is displayed.
Specifically, the load distribution fractions of the load-bearing vertical members neighboring the discontinuous transfer column are shown. This information helps to understand how the loads are distributed among the adjacent members and provides insights into the structural behavior at the point of discontinuity.
Figure 3 demonstrates this feature, allowing the user to visualize and analyze the load distribution fractions for a more comprehensive understanding of the structural response.

Verify All
The "Verify All" button provides a convenient way to perform a comprehensive verification of all column design lines in the project. By clicking on the "Verify All" button, the software will automatically evaluate the code check criteria for each column design line (Figure 4) and display the corresponding results.
...
The results of the verification process will be reflected in the corresponding cells of the column design line spreadsheet as in Figure 5.
...
The "Verify All" button is a valuable tool to ensure the overall integrity and adherence to code requirements of all column design lines in the project with just a single click.
Verify Selected
By clicking on the "Verify Selected" button located within the "Column Design" section, a dialogue box will appear (Figure 4), providing the option to select specific column design lines based on their code check status and column shape.
...
This dialogue box allows users to filter and choose the desired column design lines for verification, making the process more streamlined and efficient.
After selecting the desired column design lines, proceed by clicking on the "Run Code Check" button (Figure 4).
Upon completion of the code check process, the corresponding column design line cells will undergo a visual transformation. Specifically, the cell color will change to either green or red, as demonstrated in Figure 5. The green color indicates that the code check was successful, indicating that the column design meets the specified criteria and requirements. On the other hand, the red color signifies that the code check detected issues or violations, indicating that further attention and modifications are necessary to ensure compliance with the designated standards.
...
Showing w/o DC
The "Showing w/o DC" button in the column design spreadsheet allows you to toggle between two modes: "Showing w/o DC" and "Showing DC".
Figure 6 illustrates the “Showing DC” mode.
...
If a column transfer is present in a column design line, the column design spreadsheet will report the distributed load from the column above to the adjacent columns. This information is displayed in the relevant cells of the spreadsheet, as shown in Figure 7.
...
Ignore Changes For All
If any changes are made to the model after a code check has been performed, the colored cells in the corresponding column design lines will revert to an uncolored state, as shown in Figure 8. This serves as an indication that the code check results may no longer be valid due to the modifications made in the model.
...
The design state of the individual column design line spreadsheet will also change to "Need Verification" if any changes are made in the model as in Figure 9.
In the subsequent section, labeled as "C n," additional details regarding the column design line will be explained in depth.
...
Design Columns
By clicking on the "Design Columns" button, users can initiate the column design process utilizing pre-defined rebar templates. These templates are carefully crafted to offer optimal reinforcement configurations for columns, taking into account various design scenarios and requirements such as achieving the best tonnage or minimizing the number of rebars.
The goal of using these pre-specified rebar templates is to streamline the design process and ensure that columns are efficiently reinforced while meeting the desired design objectives. The templates are designed based on industry standards and best practices, providing users with reliable and effective reinforcement solutions.
