dold... Thank you... I agree... I understand... I "catch your drift"... I also appreciate you bringing up the tall wall stairs and use of horizontal spanning to perp walls, not ONLY in stairs, but, multiple similar scenarios! Good (related) point!

Yes! I provided the loadings.
No! I did not make that the responsibility of fabricator.
It seems inevitable that respoonsibility always comes back to either the architect and/or engineer!
phamENG... Yes! Agreed!
Thank you!
bIockhead... I agree with everything you stated EXCEPT.. that expression, "to tie it all together" is what I have heard too often!
While I can agree that the horizontal bond beam rebar "is nice", it can ONLY provide a MINIMAL, diaphragm-type lateral support action... "kinda"... for only a FEW...
Thank you ALL for your replies!
BECAUSE of your replies, I am only providing miscellaneous detail drawings waiving EVERYTHING and specifying the following...
1) Structural aluminum angle, flat bar and plate shall comply with an ASTM specification as determined by Fabricator. Architect or...
I believe, as as typical, we've wandered far beyond the OP intent and, also, answered the OP inquiry?
RontheRedneck... is that correct? Have we assisted in providing an answer for your situation?

Although we (both) SHOULD know what the ratio of reinforcement should be for CMU, due to me only having an ancient "1999 Masonry Standards..." rather than a "Building Code Requirements" for Masonry, referring to my ACI 318, and applying interpolations relative to the differences...
I've been asked to design an ALUMINUM cross-over ladder "structure", with bar-grate platform.
In over 30 years, I've never "done" ALUMINUM!
Where do I obtain Design Values for Aluminum?
Is there a "PROPER" ASTM I should comply with? B308-6061-T6? 4047? 2026? The 6-page 6061-T6 "Standard...
See OSHA 1926.502 attachment... (hopefully it worked... let me knoow if not)
+/- once every other year, I need to address a Fall Arrest "situation".

I like your detail. It certainly helps understand and visualize!
The ONLY concern I would have is the debonding agent. I don't see how a +/-(1) MIL layer of agent would prevent the inevitable movement of the steel column and, perhaps, the bracing, to come into crack-potential contact...
I've commonly heard it said, that the structure neither knows nor cares if it's residential, commerical, industrial or other!
Yes! It's YOUR home! Be satisfied in the end!
I would design for LL Deflection of L/600!
If you need to bump down, you could add pseudo wood or drywall/plaster beams...

Regarding the Steel Columnn contact with concrete, you could use a necessary thickness of expansion joint material between steel column and concrete (slab I presume?).
For the rest... Perhaps you can provide a detail?
You say, "extend the block as far as it needs to go to have the...
ForteWeb TJI Software by Weyerhauser
For decades, I understood that TJI's, in general, do not require Bottom Edge Lateral Bracing throughout the span(s), even at mid-span.
The Weyerhauser website states... Trus Joist® TJI® joists are made with no observable twist and have minimal material...

The "8" wide (nom) column", as you stated APPEARS to be a continuous wall.
NOW I see the the "NOTCH" and "BEARING" notes, on your detail, that makes me understand that the precast is bearing on the concrete wall. My oversight!
How are you anchoring precast plank ends to concrete wall...

1) I see you specified A706, rather than A615 rebar. Good - for welding! However, did you check availability?
1) I often specify F1554 Grade 36 Threaded Rod to be welded to A50 steel beams for various applications. However, in YOUR application, I would not depend on a thin 3"...
RE: Installation of F1554 Grade 36 (or other) Threaded Rod & "Epoxy" / "Adhesive" in Concrete Masonry Horizontal Bed Joints and Vertical Head Joints.

2. CAN we drill and install threaded rod with HILTI/DeWALT/Simpson/etc...
I draw (mostly) everything in Model Space.
I only use Paper Space when preparing viewports for plotting.
When in model space, although rarely, sometimes, when I zoom in, the screen turns white! then I can't see my sursor or crosshairs.
WHY?
Is there a toggle or other command to prevent or...
Thank you all for your replies!
Kootk... "MY" theory on TEK screws, in this application, is, provided the specification states that the screw must be long enough to penetrate beyond the steel structure a minimum of 3 pitches of thread, if my judgment determines that the fastened / supported...
The General Contractor wants to fasten OSB roof sheathing to Steel Wide Flanges or HSS with HILTI PAF pins rather than the specified TEK-5 screws.
Genreally, HILTI pins are for fastening light gage steel to the thicker base material, such that, the fastened material is thin, or of gage...
I don't see the plan view for your site plan, but, in order for you to provide enough gravel/soil to taper the grade enough to prevent detrimental erosion, I would think that the material cost for gravel and other "finished" earth/soil along with the labor cost for necessary compaction would...
