Good day.
I was analyzing a model and designing the plates I made at STAAD.Pro Advanced Connect Edition 22.00.00.15. After the run analysis, the result gave the above notice on several plate elements I had.
I modeled the plate elements using parametric models.
Assigned a thickness of 0.15m.
Material is concrete with an fc' of 21MPa.
Steel fy of 275MPa.
Clear Cover is around 25mm to 38mm.
Code is ACI 318-11.
I understand that the required steel for transverse moment for the specific load case exceeds the maximum allowable for that specific plate element.
But may I know how do you obtain the maximum allowable steel area required for the concrete plate element? I was presuming that we're considering the maximum steel ratio.
Or what are the other factors in determining the maximum allowable steel area for a specific plate element considering that its size varies and there were some quite small plate elements.
Thanks in advance.
