RC shear wall with opening

[Seismo123]

I was wondering if it is feasible to model a rectangular reinforced concrete shear wall with different opening sizes in SeismoStruct.

[Seismo123]

Does anyone know how to do it? How to have a custom opening in shear wall? rcrws does not provide such capability. Is there any alternative option?

[seismosoft]

No, there is no direct way to model a RC wall with openings in the middle.
If you neglect the re-bars on the projection of the opening on the rcrws cross-section, this could be a good approximation.

It would be perfect if you could add such capability, such a way that one can have a custom opening with unsymmetrical reinforcement patterns. An example of this would be a model like the figure below.



I am in need of it, desperately.
Thanks.

Thank you Seismo123, we will consider your suggestion in a future release.

Dear seismosoft;
I tried modeling the aforementioned wall. I get "Max_Tol" message. Can you check the model, please. I tried increasing Maximum Tolerance value by 1.0E+35 and had run eigenvalue analysis; but I have no idea what I should do.
Thanks.

Dear Seismo123,

Please check your element connectivity. From what I saw, many of the elements are not connected.
