    Good Day, I am currently modelling a staircase supported by a moment frame and I have come across a strange occurrence. When I checked my column forces the axial forces seemed alright but the moments were strange as the moments generated along the…
  • Cracked Properties for shear walls

    Good Day everyone, How can I account for the ACI code prescribed cracked sections in surface elements in STAAD Pro, such as a shear wall?
  • ACI 21.6.1 Requirements being applied to Gravity Columns?

    I have some interior gravity-only concrete columns that keep getting the error that they don't meet the dimension requirements of ACI 21.6.1. But why would gravity columns need to meet those seismic requirements in the first place? How can i fix this…
  • RAM Elements Concrete Wall Design Module - ACI 318 update

    I have RAM Elements 13.4.0.177, which I believe is the latest version. The concrete wall modules, both the concrete wall design and the tilt-up wall design, are still referencing ACI 318-05. Is there or when will there be an update to have ACI 318-11…
  • RAM concrete column ACI 7.10.5

    Does RAM SS concrete column design module account for additional ties required if rebar is spaced greater than 6" per ACI 7.10.5? If it does, where is that input parameter? I have several columns in my model that have rebar spaced greater than 6"; however…
  • RE: I am using RAM SS Concrete Shear Wall module and keep getting an error in my wall piers. The piers keep failing according to the maximum spacing requirements of 19.5.5.4. But the "actual spacing" noted in my section cut analysis is not consis

    A bit of a typo in your post, I think you meant ACI 318-08 Section 11.9.9.5. You can control this to some degree using Criteria - Design Criteria - Code options block, Min value of Lw to Consider: If the value input here is longer than the plan length…
