HOW TO DESIGN A FOOTING UNDER THREE COLUMNS, OR (MORE THAN TWO).

By default, ROBOT SA can design footing under 1 column or 2 at maximum, my question is how to design footing under 3 or more columns especially when we send the revit model to robot structure analysis,as in the picture i have some of the footings under three and four columns.

In this case i'd consider using my own excel sheet than the design module of RSAP.

You may also use thickness and turn on the parameter of foundationsFOTTING.PNG

What formula do you use to compute for Kz of foundation you input in RSAP? Wrinkler or something else?

So you do Qa/delta? I use the Vesic one and it has almost half of what Wrinkler gives.
