continuous footing or beam among spread footings for steel structures

[demetris.a.d]

Please help me out. I have a steel structure and after a lot of attempts i managed to get spread footings for each steel column. Now i want to use a beam or continuous footing between the spread footings Ti connect them.....please give me a solution how can i do that.

And how to i get the forces from the colums so that in case i need to design the foundations on hand...please help me out.
Thanks

Dear demetris.a.d. how did you manage to get spread footings for each steel column? Can you please tell us the procedure?

[demetris.a.d]

In the main screen structure-geometry, choose only the nodes at the bottom of each steel column and after -provide reinforcment....and then follow the tags on the right,one by one.

Typically, just under the steel column there is a concrete column with small height e.g. 1m and then underneath it there is the foundation. (Cone foundation, not flat slab)

In that case the connection of the steel column has to be done with the concrete column.

Is this possible is ARSAP? Can it be modelled as stated by demetris.a.d. with footing having a "column neck"?

DEAR Rafal.Gaweda please explain a little more, after the insertion of spread footing i do this??or i have to implement a beam??? give some details please.....much applied

[Rafal.Gaweda]

create RC Beam, apply Bar Elastic ground property to it and then it will be possible to import it to RC continuous footing module.

but how?

in the geometry section i choose my beam and then input elastic grounfd and-provide reinforcment?
i will upload my structure if you can pin point me......thanks

sorry for not understanting

A short video would be very helpful !!!
