CRSI retaining wall

CRSI retaining wall

CRSI retaining wall

(OP)
Has anyone worked through the retaining wall examples in the CRSI concrete book. I am having trouble with the stem deflection calculation. I cannot make the units correct. Any suggestions would be appreciated.

RE: CRSI retaining wall

Do you have CRSI Design Handbook 2002? If yes,check pages 14-8 and 14-9 as its all there. The typ. deflection limit is H/240. What are your soil and concrete parameters?

Yes thanks.
But...
I can not get the units to end up as inches. Numerator is ft^5 times lb/ft^3, leaving ft^2*lb.

Denominator is questionable, but lb/in times in^3, leaving lb*in^2. I think the 30x10^6 has a unit of lb/in.

Numerator divided by denominator becomes unitless.

The examples have a 1728 (which is 12^3) see page 14-17, which is changing feet into inches, but I cannot work the units out.

RE: CRSI retaining wall

On page 14-8 Ie=0.32t^3 which must have the units already included and evaluated as typically I(e)ffective is in inches^4 not ^3 as shown. I have a retaining wall program that calculates the deflection so I never even checked for the units to correspond. Nice thread. Good Luck.

RE: CRSI retaining wall

I think the fact that you are looking at a 1' width of wall may have something to do with it as well.

thanks.

RE: CRSI retaining wall

I agree with broekie.
