Plans don't call this detail out?

Pretty good sized beam, no engineer or architect to ask?

Inside web of a W8x15 should be 7 1/4" x 2"? just rip down a 2x8 and add 1/2" plywood, i run a router on the two edges to compensate for the welds

2 x 8 nominal is 1.5 inches, not 2 inches. That wont fill out the web.

In California, if you were to deviate from plans, such as using plywood rather than the called out solid lumber, the architect or engineer would have to sign off on it.

It's such a wonderful state....

I would rather put the plywood on the back, a quarter short top and bottom for the weld, and the hanger nails in the lumber.

Re: Attaching 2x6 Ceiling Joists To Steel Beam, Web Blocking


We pack out beams all the time. We use 2x maferial and plywood of varying thicknesses to flush up the outside. We normally don't thru bolt. We use 3 inch self drilling steel screws for the first ply, then nail the remaining plys on. I try not to put plywood on the outside. Another thing we do often is use saddle hangers which hang off the bolted down plate on top of the beam. We have an engineer on every job, and he has no problem with our method.
