Hi
The building is a concrete wall with a sloping roof ( semi-rigid).
There are several warning messages.
1) The sloped roof is not attached to the wall. When checking EQ_X, the shape of the deflection is as follows:
Please tell me how to check if the roof is attached to the wall.
2) Deck properties for some elements on story 1ST FLOOR PLAN for diaphragm 1 cannot be identified. No deck was modeled in some areas. These elements are not included in the analysis. Please check the deck assignments on this diaphragm.
I checked the solution note for this warning. but I properly assigned the properties for a two-way slab. And I checked the box for using beams for exterior boundaries.
Can I ignore this warning message? or Let me know how to fix this warning message.
3) Very distorted shell elements
The concrete wall has some openings away from 12" edge of the wall.
Although I removed all opening, I have still the same warning message.
Does this warning message related to semi diaphragm with slope or two-way deck?
Please let me know how to solve this problem.
Please let me know.
Thanks,
Thank you for your reference. I fixed for 1st and 2nd problem.
But I have another error that came out for node tolerance.
So I will upload my file so that you can look through it.
I think the error comes from the sloping slab and opening.
please let me know how to fix it.

Thank you, Seth
I fixed the tolerance issue.
But I still have a mesh issue
Can you look through it again?
I will upload a new model as a secure file.
You will have some distorted mesh issues with all the sloping floors, but those warnings should not be critical to getting results.
