Greetings,
Are there reference standards governing allowable checks or splits in 2x construction lumber?
The reason I ask is: very often, I'll be walking through a house under construction, and the Owner, perhaps looking to find fault with a Contractor, will question small checks or splits...
The question as to whether or not you need a license to stamp 'engineering drawings' usually comes down to local practice, precedent, and sometimes the Architect's professional judgment about their own comfort level with the building type. That's part of what being licensed is all about...
agree with structuralaggie......With regard to tall wall or 2-story wall framing, a horizontal steel tub 'belt' at mid height, tied to a corner steel column usually works.
Even easier, if the architect allows it, try thickening the wall. Vertical 2x6 LVL at 16" o.c. or 2x8 @ 16" o.c. should...
Fire treated plywood is especially prone to rot without proper ventilation.
In a code seminar I recently attended I heard of a townhouse project (somewhere on the East coast? can't remember) where the attics where not properly ventilated and the rot required a complete re-building of the roof...
"6 ways to stiffen a bouncy floor", in Finehomebuilding Magazine Jan/07 is a great summary of design ideas for increasing the strength of existing wood frame construction. I don't recall seeing any load calculations in the article, but it's a start...
Hi - I am a licensed architect looking for a good, old fashioned, shear and moment beam diagram diagram calculator. Can anyone recommend shareware? I've googled it and found some software and it's ok.
Something where you just plug in the support conditions, span, the loading (ie point loads or...
I have not heard of a "non-combustible" wood product. There is fire treated plywood. Are you sure you need "non-combustible," and not just a minimum fire resistance rating?
There's an old rule-of-thumb that says a dormer can be as wide as 3 rafter spaces without becoming 'structural', whereby the double-rafters under the dorner walls provide the same amount of wood as if there was no dormer. This yields a 4' wide dormer.
In the above problem, the 8' wide dormer...
Question about the allowable height of foundation wall on a typical wood frame residential project: does adding +1' wood knee wall above a standard 8'tall concrete wall (8" or 10" thick w/2-#5t&b) effectively cancel out the lateral bracing of the wall?
Some of my engineer colleagues won’t ‘sign...
