Slope roof area tributory load distribution

[ali07]

I am unable to model slope area slab by ETABS.
I have a beam slab system, and if i make it membrane with meshing, it gives a lot of warning messages. If i make it shell, it acts like a flat plate and laod being transferred to joints. What is the possible way to model it.
Image attached for reference.

I dont understand that if you dont want to transfer the load to joint then why are you modeling that portion of slab.

Any way try this, if you want to model this as a membrane then dont use automesh for this area.

Hope it will help.

do u think it can transfer load to the beam. The reason i don't want to use shell, it acts like a flat plate due to nodal degree of freedom, unless you have a flat slab system and no choice to do.

Question for you, can u see tributory loading to elements in slope once you assign membrane on slope members.
