Hopefully you do not have too many steps in your wall. On very long walls they can save money but on short walls (20ft or less), then I think they are more trouble than they are worth. The contractor has a more complicated form setup and has to do multiple pours usually.
With that being...
Also, in your email.... It's important to use good phrasing that doesn't get you in trouble.
For example...... which of these statements is better???
Statement 1: "There are no significant foundation cracks or evidence of settlement."
Statement 2: "No foundation cracks or evidence of...
I use 5" and 6" vertical rebar spacing on ACI 350 walls often.
For vertical bars, this is a nice setup because I can do 5" spacing on the lower half, and then transition to 10" spacing easily by letting half the bars die out. (Or I can transition from 6" to 12" spacing.)
I have not seen one in a while, but I thought that some of the Northeast USA cities (Boston, New York) had deck building codes and recommended construction details. I thought I had saved one on my computer, but I'm not finding it now. If those exist, then they could be a good source of details...
This probably doesn't qualify as 'fairly easy'..... but here's an idea....
You might be able to cut & paste all the node locations from the Staad editor into excel. (in separate columns)
Once into Excel you can divide all node locations by 12. (X,Y, & Z points).
Then re-paste all the nodes...
Who owns the wall? A governmental entity or private organization?
If private, then my recommendation would be to go through the steps of getting a geotech to evaluate; and then start saving money for a new wall.
The geotech report might serve to help accelerate the replacement timeline.
Hallelujah! Someone has found the same issue I have been wrestling with for the past 8 years.
Unfortunately, I have not found an answer. :(
I think that this is one of many glitches in what I like to call "retaining wall logic"
The problem can be further exacerbated if the geotech says...
I was a happy Smath user until late 2024. Our IT department said we were no longer allowed to use Russian based software programs, so we had to switch away from Smath.
We looked at several computational software packages, but elected to go with MathCAD. (We do work in Florida, and FDOT has...
Koot - That's exactly what we were thinking. The coupler might end up serving as a headed bar end.
We have not done any math yet, but it's possible that we do not need the full development length.
Another option is to just tell the contractor to find some headed bar ends that can be...
We have a bridge column with #11 bars in it.
Per the plans, the column bars were fully developed into the bent cap. The contractor accidently cut some of the bars 1ft short.
The contractor's proposed fix is to add mechanical couplers to the bars and then have ~1ft extensions. (the...
