The thread going tangent in perfectly fine by me, I am learning more and more from these discussions.
I would have to explain the situation more once I get home but for now I am attaching the sketch of the situation and also some sheets of the info I use for torsional...
I am trying to specify light weight concrete for a conc on mtl deck design. Vulcraft has used fc=3000 psi and conc. density of 110pcf. 3” deck with 6.5” total depth with conc.
I have three questions:
1) Is 4”+- 1” slump ok?
2) What should be the nominal max aggregate size: 1”, ¾”, ½” or 3/8”...
Concretemasonry,
Pardon my ignorance but I am assuming that by cleanouts you mean shell openings knocked into the side of a cmu block, right? And thanks for the detailed response, like I mentioned I still need to go out in the field and verify the dimensions.
And while I have your attention...
But I guess I have another question now, since it was suggested that there should be some minimal rebar in the wall, how easily can the place new rebar in an existing wall? They won't be able to dowel it into the slab but I guess that would be OK, since shear at the base of the interior wall...
Mike & Mike, gracias. I am in Chicagoland so seismic is not an issue, and I have seen notes on drawings from a couple of engineers where they say no reinf required for 6" interior wall upto 14' as long as its braced on top.
Interior cmu wall, non-load bearing, probably 6” cmu x12’ high but still need to verify.
For access purposes they have to demo about half the height and then re-install matching masonry. Since most likely there isn’t going to be any rebar in the wall, I am just going to let them install the new...
JAE, thanks for the info. I'll be noting this down and studying up on it. The wall in question is 4" cmu and is 10' tall, braced @ top. I know that 6" interior wall can span upto 14' without reinf but I am not sure about a 4" cmu wall.
I was wondering if anyone can take a look at the situation I have here (using 9th addition):
Existing W36x135 (fy=50) girder, with 45' trib on each side, and 30' span. 3/4" studs @ 1' oc.
hr (rib)=2", total depth of deck=6" therefore, Y2=4".
Actr=4"x(45'/4)/8=67.5......where 8 is my n value for...
I am designing an interior masonry wall for some lateral load and I have determined that I need very little rebar. Is there a maximum rebar spacing limitation in the code somewhere, because I would like to place the bars @ 72" oc but I have noticed that most engineers tend to place the bars not...
