A. The critical issue with built-up beams is that all the layers must deflect together and by the same distance in order to be properly sharing the load. For beams where the load comes down evenly on top of the beam, such as drop beams or beams directly under bearing walls, the nailing pattern is ...
The two beams you can make out of 2-by-10 dimensional lumber are double beams and built-up beams. A double beam is simply two lengths of lumber that sandwich the top of a beam. Built-up beams are boards nailed together.

tripple 2x10 beam construction By code I will need a triple 2x10. for the 9ft to 11 ft span I can use 20ft long 2x10's however to cover the 2 11ft sections I would need a 2x10x24 which I cannot get. Can I sandwich 2 12 ft long ones with the seam being almost half way over the middle 11ft span?
Should use 2x10 for beams but 2x8 will be fine as well. If you are worried you can triple the 2x8 for the beams but double will be sufficient. You should put the beams at 7 and 14 feet out from the house, with the piers you should do 3 per beam with spacing of 1, 7, 13.

The distance you can span a 2-by-10 joist without additional support depends on the species and grade of the wood, how far apart the joists are and the expected load on the joists.
