Toeless Cantilever Retaining Wall Strut and Tie

[mchen96]

I have a question regarding the design of the connection of a toeless rc retaining wall. I've seen this post and I'm well aware that the detailing of the joint for toeless retaining walls is more elaborate than just developing the bars.

Does anyone has a strut and tie model sample for fig 13-29 without the diagonal bar? Alternatively, does anyone know any good text or paper that covers opening joints?

I'd like to calculate the moment capacity of the joint instead of blindly using the reinforcement ratio to efficiency table in the image. Does anyone have any good examples for this scenario? Alternatively, what is the industry practice for designing toeless cantilever retaining walls?

- suggested STM below.

- I'm unable to supply a worked, numerical example because, frankly, it would be too time consuming.

- the STM relies heavily on Klein's curved bar node concept as discussed in the thread that you mentioned.

- WRT detailing, the answer is very much small bars and a large joint.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
