This looks like an older detail. It is hard to evaluate the retaining wall design without information about soils. "French drain" deserves a separation from the rest of the backfill with a 12" diameter gravel fill wrapped around with textile fabric. The driveway shall not be placed over the...
Does the Building Code allow the use of adhesive sealant instead of mechanical fasteners to attache the wall base to floor structure?
I am trying to find an approved adhesive sealant to use it for attaching the base track to stone tile floor.
I cannot use any penetration in to stone tile.

I would like to thank everyone for their input.
Your thoughts and opinion helped me understand the issue in much more details.
In conclusion, I feel more confortable with independent action then with composite action.
Gentlemen, I thank you for your contribution. Your input is highly appreciated.
Let me recap just to make sure that all of us are on the same page.
Two statements that have been advanced are:
1) the loss of partially composite action is indicative of failure
2) your 'way more elastic'...
Since all three layers have the same thickness, and silicon is way more elastic than aluminum, wouldn't it be accurate to assume that the top and bottom (aluminum) plates shall deflect independently even if there is no failure ?
Two 1/8" aluminum plates are glued together with a 1/8" thick silicone.
When computing deflection should I conceder it as a combined shape or laminated ?
My loads are low in my opinion,
15'x48'x20 psf = 14.4 K
so the seismic lateral force is less that 5K.
And the beam+post connection will give some resistance.
Thank you very much for your comment.
Thank you for the clarification.
My project is a proposed deck attached to an existing two story wood framed house.
Steel posts with grade beam could be the next choice, but the owner/builder wanted to use wood posts.
I assume that Figure 4B will apply. Is it required that the entire diaphragm...
When detailing Newport Tool & Fastener (ICC-ES WSR-1411) to anchor the roof tile straps to 3" roof concrete deck the building official raised concerns about Simpson Titen HD screws I had specified. This product is approved for dry condition interior use only. I've proposed Tapcon as an...

I only red the beginning paragraph and have had enough. Lets compare us with an athlete who is about to break a record. He/she has the "competence" to be the challenger, he/she also has the "confidence" that he/she can do it. But what is going to happen is a mystery yet. He/she may become the...
Thank you JAE!
I see it in ASCE 7-06 12.2.3.1 EXEPTIONS:
Section 12.2.3 Combination of Framing Systems in the Same Direction. answers other part of my questions.
I need an advise on using one R for the roof level, another for north and south directions.
Is there a provision about this? I am designing a two story light frame building that has a 40' long steel beam providing the required turning space in the garage. If R=3 is used for the entire structure...
Balcony structure W=4155LBS
Cs=0.274
V=0.274*4155=1139LBS
Mov=V*L/2=1139*12/2=6834ft-lb
T/C=6834/18=398LBS
Simpson's LLT19 LA RR25818
allowable load is 825*0.75=618.75LBS
If this is correct, do you think I can use LLT19 with 1/2" bolt through existing 4x12 or 2-2x12 2nd floor framing?
Thank...
I am designing a rectangular balcony structure( see attached pdf plan), that is attached to the existing house on one side and is supported with two 6x6 wood columns on the far side. Can the rigid horizontal diaphragm be designed so knee braces are not required for the far end latteral support...
Thank you all for valuable comments!
I was using the same source for thermal coefficients, and (my mistake) 4.7 is for steatite one row above steel.
The expansion to be counted is now 0.5in if aluminum goes from 0 to 100 degrees Celsius, and steel maintains its temperature.
I am also going to...
