I'm building a 10" ICF garage wall with (3) 9'-0" doors. The column space between each door is just 14 1/2".  In one of the spaces, the plan calls for a 12 x 22 steel beam to bear.  I am concerned that a 14" x 10" concrete column (with 4 vertical #6 bars) will not be sufficient to carry the beam. I wonder about putting a lally column inside the space and pouring around it, encasing it. Two questions- would the concrete column alone be sufficient to carry the point load of the beam? Would the insertion of a lally within the pour negatively affect the concrete via shrinking, expansion/contraction, etc? 
All suggestions are appreciated. Just want to get a few opinions before I visit the engineer. Thanks

You really think the weight of the beam, plus whatever else above it is supporting, will weigh more than 490,000 lbs? 10" times 14" times 3500 lb/sq in = 490,000 lbs. Check with your engineer. From a pure compressive load standpoint there shouldn't be any problem. Just make sure that the load on the top of the column isn't enough to cause failure by column bending. That can occur well before pure compressive failure. I doubt there will be a problem considering the column is only 9' tall. You'll also want to be sure the load is distributed uniformly over a good percentage of the top of the column, i.e., don't try to transfer the load of the beam to the top of the column with a 2" square steel pad! That's an absurd idea, of course, but you get the point.

Minimum column size should hold 10'' concrete. It's been tried and tested. We also do the top beam out of icf all the time with stirrups and upsizing bars depending on width of opening.
Cheers!
