S-CONCRETE squat shear walls longer than 15m

Hello,

Question about S-CONCRETE.

I am designing some very long squat shear walls. I have found that in S-CONCRETE, whenever the wall length exceeds 14999mm, the box under Wall Reinforcing>Panel Reinforcing> "Include Vert Bars (N vs M)"  is greyed out.

I am referencing CSA A23.3-14.

Walls with a height to length ratio of less than 1.0 are not permitted to consider the contribution of distributed vertical reinforcement towards the moment resistance, so I would like to uncheck this box, but am unable to do so.

Can you anyone advise on why this box is greyed out and if there is a way to analyze squat walls with a length greater than 15m in a code-compliant manner?

Thank you,

Jackie

    Hello, Jackie,

     

    Thank you for reaching out.  We couldn't replicate the behavior you are reporting here, can you please share some screenshots from your Section window and Wall Reinforcing window? We can review and work around them to provide suggestions for your current inquiry.

    Thanks Alejandro, please see screenshots above. I don't think I changed many things from the default, except for the wall length, and the rectangular/symmetric buttons.

    I've noticed that it's not 15m specifically, but when hw/L1<2.

    Thank you for sharing this info.

    Unfortunately, we couldn't replicate the reported behavior. May I ask you to share your model with us? We can take a closer look at it.

     

    Additionally, you can open a ticket with the info shared so far, so we can keep working in this case. The ticket can be opened through the next link:
