Plotting Interaction Diagrams

The Plot Interaction Diagram feature allows users to plot Interaction Diagrams for Pile Sections. This feature is available Axial, Lateral and Group Analysis if there are piles with Reinforced Concrete sections.

To plot an Interaction Diagram:

1. Select Results > Plot Interaction Diagram (or if pile is placed in Plan View, right-click the pile and select Plot Interaction Diagram). The Plot Interaction Diagrams dialog will appear.
   
2. Select the pile sections you want to plot the interaction diagrams for or click Select all to select all available pile sections.
3. Use the Angle field to enter an angle if its something other than zero.
4. Use the Load field to enter your Load value.
   
5. Click OK.
   
   The Interaction Diagram window will appear and you can see the results:
   
   

Inputs

After generating the Interaction Diagram, you can use the Inputs section of the Charts tab to update the values in the diagram.

Use the Input options to:

• Change the Angle or the Load using the fields shown above.
• Deselect a Section using the drop down menu.
• Plot Factored and Unfactored Graphs by checking or unchecking the checkbox.
• Change the number of points to construct each plot by clicking Number of Steps
  

Click Compute after making any change to the above options to recompute the results.

Note:

• To be sure you don’t lose your previous graphs, export them to Excel before you change the input parameters using the Export to Excel option.
