Good afternoon Bentley Team,
We are modeling a 4 story wood frame on top of a transfer concrete podium. Though we understand that we are not designing the wood framing in RAM, we would like to accurately model them to obtain the most accurate load transfer onto the slab. In doing so, we are obtaining the following warning for every wood frame wall above the transfer slab. We would like to make sure this warning is due to the fact that the wood frame wall can not be modeled in RAM, but that the gravity loads (and lateral) are correctly transferred to the slab. In designing the slab on Concept, we obviously see the line loads corresponding to the walls, but want to make sure we are not misunderstanding the software's analysis. Attached is the 3D model, and a screenshot of the warnings we are getting. Any input would be appreciated. I have also added a link to the model itself.
Thank you,
Structural Model
Hello Jak. Your understanding of what's happening appears correct. The reason the warning is being delivered is to make sure you know there are walls and columns that are sitting directly on a slab with no beam or wall underneath helping the load transfer. The load is accounted for and applied to the supporting slab (the 2nd level slab in your case). We deliver the warning since we don't do strength checks for slabs or decks in RAM Structural System, and so it's just a reminder of sorts to make sure it's checked.
