I'd take the gluelam any day over the PSL, those things deteriorate when exposed to any moisture. Whenever I've had PSLs specified I go to the engineer and have them change them to glulams or steel.\ said:
When it comes to engineered products, smaller does not automatically equate to inadequate.
All shear panel breaks require a minimum of 3x studs and blocking, 3xs are becoming so common that I see truck and trailer loads of nothing but 3x material going down the freeways. This may be only in our seismic zones but it is a good requirement since nailing schedules require 10d common or .148 gun nails. Back before this requirement I was splitting studs and blocking with all the nails, I've had 2" o.c. specified in some nailing schedules, but even at 4" o.c. two of them going into 1-1/2" studs splits the studs.e hilton said:
My father runs a farm store and had someone design a front canopy for the store to make it look less industrial. They specified all PSL columns and beams. Now, these were going to be wrapped with aluminum, but otherwise exposed to weather. He asked for my comments on it and I told him his building was going to melt. When I asked why they didn't just use regular dimensional lumber he said the architect said they liked PSL better. the architect was trying to make the store look overly commercial, which is not great for a farm store where your clients usually come in directly from the barn to grab something. He had me re-draw the plans and I tried to make it look more like a barn, exposed roof rafter, exposed beams and columns. Also cut the estimated cost of the project by a third. I still find it surprising when certain products get specified by a "professional" where they really shouldn't be.conarb said:
Chapter 9 of the IBC is Interior Finishes, specifically, the material of those finishes. See Section 801.1. If a plastic cove base is being installed (which I suspect that this thread's originator is talking about), you would need to look in this Chapter for compliance of that material to the code.GCtony said:

If it's a shear wall it doesn't, if it's not a shear wall it doesn't. In our seismic zone the prescriptive code is out, everything requires engineering. They all use the irregular shape requirement to require engineering since the 1998 UBC, examples 1) I tried to permit a simple dormer on the roof, CBO says get an engineer loads may not go all the way straight into the ground, he was correct, when the engineer crawled under the house there was a 3" offset under the first floor. Example 2) On a home I built 30 years earlier the owner asked me to remodel the kitchen, I tried to get by without engineering by just changing cabinets, during the work the wife asked me to raise a doorway from 6'8" to 8', bearing in mind what the CBO had told me I tried to disguise what I was doing, used same header, old studs cut for new cripples, straightened and used old nails. etc. When I called for an inspection on electrical and plumbing the field inspector came into the house looking for anything structural, he saw the header change and shut me down, I told him I was going in to argue it with the CBO, he said get an engineer, $700 and three weeks later I brought the engineering in, he didn't even look at it, just shoved it into the file and said: "Now aren't you happy? We now have engineering to protect both of us in case anything ever happens." It's liability thing, AHJs want everything engineered so there is no way they can be liable.MASSDRIVER said:
Particularly if you split the 2x studs and blocks, the engineer or inspector may make you replace them with hundreds of 10d nails in them.MASSDRIVER said:
