PY Curves for Tiebacks
PY Curves for Tiebacks
(OP)
I am trying to model a drilled shaft wall with tiebacks. The manual does not do a sufficient job in explaining their examples of PY curves for their tiebacks.
Any help in how to model the PY curve for tiebacks would be great. Thanks.

The spring stiffness(K) is
K=AE/L
Where
A= Area of tieback bar or strand ft^2
E=Molulus of elasticity of bar/strand kip/ft^2
L=Length of unbonded tieback (ft)
Make sure you account for the direction of the anchor.

The py curve for the tieback was entered as linear. The slope of the curve is the yeild capacity/yeild deformation.

Note thaqt the quality of the answer for such an analysis is dependent on the quality of your soils information. A hand solution may be just as accurate, if not more, and might be easier.

I agree with DRC1. The PY analysis for a tiedback wall sounds like overkill to me.
