I've not tried this approach, but it seems to me you could treat the concrete as a continuous brace system for the steel column. You'd have to decide if it's cracked and what the Icr is going to be, and then prove that the concrete portion of the column alone can provide the strength to resist...
Well, if he takes it straight down, that's true. And even if he continues the cable in the same plane, there's some horizontal component applied to the support as the cable deflects, but it's going to be much more manageable. When I said "downward" I was thinking laterally and downward, such...
Aren't the S beams supporting the tiles already on their bottom flanges--and if those lines in between the tiles are the end of a steel tee, wouldn't the tee orientation be the opposite of what you'd expect?
Maybe it was obvious that those 'lines' are steel when you visited the site, but if I...
The cable won't be deflected 2" in the final position, so the loads will be closer to those in the 24" position, as you noted in your original post.
I believe you can use the principles of cable barrier design to get what you're after...
Make sure you get a separate mix design submittal for the 3/8" mix--you need concrete with 3/8" agg that meets your specs for A/E and such, not whatever masonry grout mix the local plant is turning out.
Also, I'd make sure he's not going to backcharge the project for the difference--with the...
Good Lord. The entertainment value has pretty much vaporized now, hasn't it?
I went to grad school with Robert Frosch. I'm sure he'd love to know he had a walk-on role in that thread.
I've been too distracted (read: cheap) to buy the new 08 code. What does 15.10.4 say? The updated (to 08) PCA...
That linked thread was actually entertaining.
10.5.3 specifically references 10.5.1 and 10.5.2. It would appear, based on the language, to be a stretch to apply it to 10.5.4.
But really, how much lower than .0018 do you want to go?
In the past, I have checked buckling of pony trusses by providing some fixity at the base of the vertical web members, and counting on them to cantilever up to brace the top chord. You then have a discrete brace system where the stiffness of the cantilevered web member is critical, including the...
If the column shortens along the length of the rod, but the rod does not shorten, or not as much--it wont' creep, but if it's tensioned will lose some of its elastic extension--, then the nut could lose bearing contact. Am I thinking about that wrong?
Here's my thought process.
1. Don't want...
Yes, you'll want an angle frame under the deck to take the curb loads. I generally then treat the load to be taken completely by the angle frame, which delivers point loads to your joists.
Without the angle frame, a concentrated load on the deck could cause it to deflect and pull the...
Kootk, the creep I'd expect is just the concrete "relaxing" under the load, and the only thing I don't want to happen is for a snug-tight nut on the top of the anchor rod to be able to work loose over time. The beam is cantilevered at a roof condition, so uplift on the underside of the...
You've basically got it. It's not shear being applied but pure tension, as the steel beam will sit on top of the column. Unless you're simply referring to the bond stress along the anchor as a shear stress.
My question is really one of what methods are employed to develop pretension in embedded...
