True. I just thought maybe I could assume worst case and get away with it. We have a meeting about what we are going to do with it today. Thanks again all for the replies.
"The best advice given so far is to hire a geotechnical consultant and base the design on Ko conditions."
I agree and we may just have to do this. That was my original question really. Do I need an investigation or are there standards that I could use. So, my answer is do the geotechnical...
Thanks all for the replies. I guess saying it was ornamental was the wrong way of describing it. I'm getting help from my senior engineer here and we'll see what he says. Again, thanks all for the help.
Thanks for the replies all. I'm going to use 120 pcf and 32. It's only an ornamental retaining wall at a university. Should I even spec compaction? Or even something smaller than 95% compaction?
Just curious: Why do you say to use Ko conditions? Isn't that for a restrained wall? I'm...
Yes, we are going to replace the existing wall with a reinforced concrete retaining wall with a brick veneer.
It's in Lancaster, Pennsylvania, so siesmic considerations shouldn't govern I think. Wall height is 12 feet at the apex. No additional loads. Thanks for your help.
Thanks Gimbli. What we are doing is taking an already built retaining wall (brick)and re-designing it with reinforced concrete with a brick veneer. Do I need to have a geotech investigation performed?
I'm designing a retaining wall. I'm going to assume that the soil behind the wall is compacted fill. Can I use a standard density or do I need to test the soil to be more accurate? Also, what angle of internal friction should I use for the backfill? Thanks.
Good point. I am assuming though that some aspects would be redundant and would not need to be drawn umpteen times. But yes, there are probably a lot of drawings for it. Wish I could find just one though.
Thanks Sam and Eddy. I'll look into these. Any Idea what this book was called by any chance? I'll do a google and if I find out what the book was called, I'll post it here. Again, thanks.
I don't need them per say. I'm studying for the P.E. exam and I thought it would be something that could keep me interested and educated at the same time. I mean no offense to anyone that lost loved ones that day. Should I ask the Port Authority for copies or NIST? Would they even give them out?
Can someone help me out in trying to obtain the original construction documents to the World Trade Center Towers and possibly WTC7? I tried a search for this topic but didn't show anything. Thanks in advance.
