Retaining Wall Failure - Deflection or Angle

Retaining Wall Failure - Deflection or Angle

Retaining Wall Failure - Deflection or Angle

(OP)
Is there guidance for a deflection (offset) or angle that when a retaining wall has reached those values, the retaining wall is considered to have failed?

Thanks in advance.

RE: Retaining Wall Failure - Deflection or Angle

I use L/240 criteria to limit deflection at the top of the stem, but that is not anywhere near a failure value.

RE: Retaining Wall Failure - Deflection or Angle

hmmm... I imagine it would depend on what the governing code or industry standard possibly. What type of retention system is this?

FE - thanks for tip by the way.

LADOTD, use 0.4H where "H" is the exposed height of the retaining cantilever wall.

RE: Retaining Wall Failure - Deflection or Angle

TIA30:

I assume you mean 0.04H as 4 feet seems a bit much for a ten foot wall. Just a bit.

No. You apply as:
Maximum Allowable Deflection = 0.4 (Exposed Height in feet) = Results (inch)
