I have a multi story concrete structure that I am using RAM structural to model. The majority of the structure is post-tensioned slab, with a couple areas that are 1-way slabs with beams (at an elevated pool deck). I have seen in some posts that it is not recommended to mix 1-way and 2-way slab in RAM SS.
I am wondering if I should model the slabs as 1-way and 2-way slabs, or should I model all the slabs as 2-way and adjust as required? I am running the diaphragm as semi-rigid.
I am concerned that the 1-way slab is not distributing the lateral load properly through as a diaphragm, which results in larger story/building drift. If I have a 1-way slab on gravity beams with 2-way slab around the area, does the 1-way slab transfer the lateral load (contribute to the diaphragm) if run as semi-rigid?
If I model all the slab as 2-way, I am concerned the gravity load is not being distributed correctly to the gravity beams in the 1-way slab areas.
Any recommendations for how to model this type of condition in RAM SS and ensure that the loads are being transferred accurately?
Thanks is advance for any assistance you can provide.
