Problem to design RC walls and required/provied reinforcement

[iago_b_nojosa]

Hello everyone

Hello everyone,

I would appreciate some assistance with designing a retaining wall in RSA. After reviewing several forum threads and watching available webinars, I’ve encountered an issue that I can’t seem to resolve.

When I complete the model, apply the soil pressure load, and run the required reinforcement analysis, the results indicate a certain amount of reinforcement is needed. However, when I use the provided reinforcement tool, it doesn’t generate the required reinforcement as expected. What could be going wrong?

I’ve attached the model for reference.

Thank you in advance for your help!

Best regards,

Hi @iago_b_nojosa 

Set the wall as "Floor"

Hello, @Simau

Thank you for your response. However, setting the wall as a floor leads RSA to design it as a slab rather than a wall.

I acknowledge that the reinforcement provided by RSA (when modeled as a slab) satisfies the required reinforcement (which was my initial issue). Still, is designing it as a floor/slab the correct approach for a wall in RSA?

Additionally, I’m using EC2 for this design.

Looking forward to your insights.

Best regards

In your case, it is more of a slab than a wall.

The out-of-plane bending moment is predominant compared to the vertical loads.
