I am modifying the model by increasing the thickness of the slab.
Sorry I dont get the question here, I think the uplift is caused by the truss action in the full model.
I get that the transfer slab is too soft and I am trying to re-check its deflection when taking construction sequences into consideration to see how thick it has to be to make the deflection reasonable small.
The model is actually more than 2 stories, like I said it is a simplified model. And...
Thank you very much everyone for your full explanation. Appreciate that. I think I am getting the ideal.
So does the following method sound reasonable?
1. Add Sequential Construction Case (dead load included only) in Etabs, lets name it 'Real_DL'.
2. Run Etabs and export the 'Real_DL' above and...
I think you can simply revise the out-of-plane stiffness by changing the stiffness of m11,m22 and m12 to 0.1 when defining the wall sections. There is a stiffness modifiers option.
Thanks KootK. I wonder what location is this beam going to be? because looks like you are connecting the beam to walls above not below. (I reckon you thought these two walls were at lower level and arrange a beam to pick up the middle wall above?)
May I kindly ask what the purpose is of doing...
Okay, I have uploaded the ETABS and SAFE model as below

This makes sense. So if the layout cannot be changed, what should I do in Etabs before exporting to SAFE to make the transfer loads 'normal'? ( I don't think I can use the above 'weird' loads to design the slab directly, can I?) I have tried to revise the stiffness of walls but doesn't make much...
So I have simplified my model to make it easier to look. I am using ETABS for this building and use its export feature (loads above and floor) to SAFE to design the transfer slab on first floor.
I then found this weird thing, though the internal transfer wall is in compression in ETABS, the left...
