Tie-Back Wall Model in ABAQUS
Tie-Back Wall Model in ABAQUS
(OP)
I am working on a simple tie-back wall model to get the general set-up working before moving to a more complicated one. I have a soil body, a concrete wall and a tie-back anchor rod modeled as a beam. The anchor wire part is segmented, with one end embedded in the soil body and the other end embedded in the wall. A bolt force of 100KN is applied in the mid-section of the anchor to simulate pre-stress in a tie-back wall. Gravity loads are applied to simulate the at-rest behavior of soil behind the wall. The problem is that the simulation does not converge after the contacts are established. Can someone take a look at the model and till be what I am doing wrong? I have a geotechnical back ground and I am moving from Plaxis to ABAQUS for more advanced modeling, but I am basically a self-taught ABAQUS novice.
I appreciate your time and help

With your soils background, why not take a trapezoidal earth pressure distribution and then use the free earth or fixed earth method to obtain your tieback force? Anyhow, Foundation Engineering 2nd ed of Jumikis has a nice coverage of this topic.

If someone can take a look at the problem set-up and tell me what I am doing wrong or give me tip I will be most grateful.
