Variable Cap Parameters Screen

This screen appears if you selected the cap shape as variable. A variable cap has different section heights along the cap, and Substructure assumes that the centerline of a variable cap is a straight line passing through the mid-height of the smaller of the two ends and parallel to the top surface of the cap.

To define a section:

Input the elevations of the extremities of the cap, depth, and skew angle.
Input the height of a section in the Height field.
Input its location from left end of the cap and each successive section, in the Dist. From Last field.
Note: In the Dist. From Last field, you can specify the current section location referring to the last section.
Click Add. The section will be added to the list on the screen.
Repeat this procedure to add additional sections.

You can modify any section location and height displayed in the list by highlighting it, making the appropriate changes, and clicking Modify. To delete a section, highlight it and click Delete
