The Longitudinal Reinforcement tab is displayed when the View/Update dialog opens. The grid on this tab displays the selected bar pattern from each bar pattern group tested and shows a "final" pattern. The Final pattern is the best design for the entire column line. It is automatically selected from the list of assigned bar pattern groups. The final design is selected from the group with the smallest reinforcement weight and when applicable the least number of design warnings.

To analyze a bar pattern, it must appear in the Final column. Alternate patterns can be selected from the final column drop down list or patterns can be moved there from one of the pattern group columns. The list final column drop down list contains a list of all the bar patterns that have been generated from the defined bar pattern groups regardless of whether groups were assigned to the column or not.

To move a pattern, click on that pattern and then click the Move To Final button at the top of the column. Once a new pattern has been selected, click the Analyze button to analyze the reinforcement.

The interaction diagram Surface: The diagram on the right side of the tab shows the column interaction surface at a given angle. Below it is the angle of the diagram and the list of all the design points checked for that angel. The angles are grouped in 2 degree increments. By default the angle and data point selected will be the ones for the selected story and pattern's controlling data point. Changing the angle will bring up the appropriate interaction surface and design points.

The crosses + in the diagram identify all the checked design points. Selecting a data point in the list below the diagram will automatically move the slider to that point. The column axial capacity and corresponding moment capacity at the location of the slider for the given angel are displayed under the diagram. The slider can also be moved manually by left clicking and dragging the slider ends.
