In my county of Northern Illinois code is that all decks wether connected to the house or not require a 42″ minimum concrete frost column.
The grade in the area is 12″ from top of foundation. What type of connection should I use to attach the beams to the top of these concrete columns as they will basically be resting right on top. I looked through the Simpson book but could not find anything specifically for this.

Gerard,
Try using a post base. Most post bases are 3-1/2" wide so you can use a double 2x beam with 1/2" plywood spacers to give you 3-1/2". The spacers will help you get airflow around the beam which will prolong it's life. Remember to cur the tops of the spacers at a 15 degree or so angle to facilitate run-off. Good luck.
