Coupled shear walls with diagonal reinforcement

hello team
thanks for the reply
now i am facing an error while trying to run the model "invalid type of element or number of nodes".
i attached the model for your kind review

It's because your mesh is a mix of quadrilateral and triangular elements, but the ASDShellQ4 is only for quadrilateral elements.
Try to make your mesh all quad or all tria

hi again
I have made significant progress in aligning the numerical results with experimental data. However, I have encountered convergence challenges, particularly around the 60% mark of the analysis.
Please take the time to review the model attached and provide me with following:
1. Clear instructions on how to have better matching between the numerical results and experimental results specially in the elastic range where you can notice that the base shear results are greater than the experiment
2. Guidance to reach 100% Convergence as It is stopping at 60% although I have increased the number of steps to 600 and using fine mesh

Hi, I want to look at the boundary conditions for the specimen to verify if that aspect is captured correctly in your numerical model. Can you please share the specimen setup?

[farisuwais]

please clarify what is meant by specimen setup as i have attached the model

[farisuwais]

i have added the other files as will to the RAR file

I understand that you have shared your numerical model, but I want to check the experimental setup to verify if the boundary conditions in numerical model is properly captured.
