The previous owner did something I nor anyone else I know had ever seen. He pored a concrete elevated deck. Anyway I'm tearing it out because I'm getting some wood rotting due to the concrete. I will need to replace the header/beam/girder (lots of rot), the long beam that spans the from pillar to pillar. The span is 14 feet. That beam was a left over log from the house, 6"x7" (it's a log house). See picture below.
Anyway I have calculated I can double up 2 2x10x16's and make the span work. My question is this I have a bunch of 2x8x16's. Plus the 2x8's would look better for a number of reasons, additionally I have no idea how I'm going to get the 2 2x10x16's to the house. I friend picked up the other decking, but now he's out of town for the next 3 weeks. My question is this, can I triple up 3 2x8x16's? If I can't, I would be curious as to why I can't.
