The nail gun may punch right thru it. An option I have used when they forget the ridge straps and don't want the flat area is to use a Simpson DTT1Z at at each rafter.
It is unusual around for a GC not to pull a permit as they will lose their license if caught. Plenty of non-licensed/homeowners do, however. Many get caught though from neighbor complaints. It also can come back and bite them when they go to sell the house as most real estate agents check for...
No way you are getting that to work in real life.. Even if it calcs out, you will eventually have a sag at the cant. and a hump in the middle of the floor. Ask me how I know :)
As KootK mentioned, I will use the upside down hangers at point loads. I am doing one now where I have a ridge load coming down. I used a cont. 9 1/4 LVL for the band and upside down hangers - except I put a dbl. joist under the ridge and used a right side up hanger to get the load into the rim...
I have never used PT for this. I don't think the hanger is needed unless the wall loads are hugmongous (which is unlikely if your cant. actually works) . Might want to block every other or third joist bay at the fdn. wall though.
Is it any worse than any other residential dropped beam? I have a lowered ceiling (not shown) on the left side flush with the bottom of the beam if needed to resolve the torsion. Just curious of other's thoughts w/o the ceiling.
Never done it in-situ although my steel guy has done that for me. He uses what is called a reamer bit in his 1/2" hand drill. Drilled 4 holes in about 1/2" thick material in about 15 minutes.
Not a contractor but have built 3 houses for myself that contained a fair bit of steel. It does take...
If you are trying to save money, they can be field drilled. Just need a nice drill, some good bits and oil. A Drill doctor is nice to use every 5 or so holes to sharpen up the bit. Start with 1/4"Ø and go to 3/8" and then 1/2" Time consuming but actually quite cathartic (for me anyway). I have...
I have honestly never done this as every I-beam I have ever designed was serviceability controlled and not even close to yielding - especially now with 50ksi the norm.
