ACI 318-63 What is the allowable compressive strength of plain concrete for WSD
ACI 318-63 What is the allowable compressive strength of plain concrete for WSD
(OP)
I am designing a CSM wall. we are using Plain Concrete provisions as there is no codes for Cutter Soil Mix walls.
I am using working stress design, to get a safety factor for applied stress over allowable stress.
I need to find the allowable compressive strength of plain concrete
I see factors of 0.6 and 0.45 and even 0.33 times f'c, but no solid reference
Mostly papers I can find on the net. I don't have a copy of 63 code.
I am sure they have it there.
If anyone can help , I will be grateful
Thanks

What's a cutter soil mix? Is that a soil-cement mix?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Buggar, Yes it is soil-cement mix. Based on test results 900 to 1000 psi is used for f'c.
I needed the allowable for working stress design so I can calculate the safety factor,but as dcarr82775 suggests
factors 0.4 or 0.45 is used for f'c to get that WSD allowable. I don't have 89 code but try to find it to see.
thanks again

I couldn't access that link at work..Somehow it is restricted...Can you write the web address so I can go directly there,
or use VPN client to get around it.
Thanks
