Retaining Wall Keyway
Retaining Wall Keyway
(OP)
Looking for information on keyway resistance capacity in retaining walls to resist shear.
30 ft high RC R/W with berm height of 22’-0”. Anticipated shear load at footing is 25 kips. Contractor intend to use keyway at footing level. Trying to size the keyway which can resist the shear at joint location. Insight or experience appreciated.

footing into the soil = soil key

But yes, simple shear calc.

I have a 1973 textbook of his right here. ($17.50, can you believe that)
Reinforced Concrete Fundamentals.

By any chance do you have that funny essay by Russell Fling, where he compares concrete beam design by ASD to USD, saying USD is nonsense?
RE: Retaining Wall Keyway
Shear Reinforcement, Avf = Vu /[ (Phi=0.9)*Fy * (Shear Resistance = 0.6 for concrete)]
Calculate the reinforcement size required per lineal ft and provide a bar shared between footing and the stem with standard hook both end. Did anyone has experience using this method.

I used to do concrete (a long time ago) - then it was all steel - now all wood. grrrr.

The definition of a structural engineer: overdesign by a factor of 1.999, instead of the usual 2.

The other mentions of shear in Fergie's book are scattered all over (of course).
I will study them tomorrow when I get some time.
Darn good book; I wasted money on 2 steel design texts that are incoherent blather.
