The Story - Analyze tab in the investigation section of the View/Update dialog is where you can try various sizes or yield strength values on a per story basis. If several stories are spliced together, these stories are investigated as one unit.

Upon entering the View/Update dialog the size and yield strength on the Story - Analyze tab reflects the selected story.

The yield strength value can be changed by typing a new value in the edit box.

The size can be changed in one of two ways:

1. Click on any cell in the grid that contains a column size. This size will be transferred to the Story - Analyze tab, even if the cell is not associated with the selected story.
2. Select a new size from the combo box.

When a new yield strength is entered or a size is changed by clicking in the grid, the View Results button and Select buttons will be gray out until an Analysis has been performed (Click the Analyze button). This is also true when changing the properties of double angles for hanging columns.

Selecting a new size from the combo box automatically kicks off the analyze process.

When results for an analysis is current, the resulting interaction equations are displayed at the bottom of the tab. In cases where the analysis fails, a reason for the failure appears in red.

Clicking the View Results button displays the Column Design report for the size and yield strength chosen for investigation.

Clicking the Select button transfers the current size and yield strength to the "Final Design" section of the table. An analysis of the entire column line is then run to update the weight and interaction equation values for all columns. If any design warning occur during this analysis, they will be listed in the Design Warning list box.
