Within the column module of StruCalc there is the ability to calculate a cantilevered column. 

The column module typically assumes a pin-pin connection for the end supports, but the end condition can be changed to a cantilever inside the module.  Once a cantilever has been designated by selecting the Cantilever Column checkbox the Column End Condition or K(e) value will change from 1 to 2.1 and the top of the column will then be unrestrained.

This is particularly useful for posts that are supporting lateral loads of some kind such as:

• pole barn supports
• car port supports
