how to add/design foundation for shear wall

[oliverkisera]

Hello , I have question here, I have modelled my shear walls which ive grouped as core walls that will carry the elevator shaft, how to i add the foundation for the core walls , so should it look like a rectangular mass slab where the core walls rest, how do i do that, thanks in advance, ive attached the model

Hello people, is it possible to add a combined pad footing around the corewalls, i modelled the corewalls as RC WALLS and i dont know how to add a combied rectangular pad footing around there, please help me please, thanks in advance

Hi @oliverkisera ,

Just create a slab below your walls using the Floor or Panel command.

Thanks a bunch, you saved my day, please kindly allow me to ask one more thing, its really disturbed me for long and youre my savious,     Hello people I have modelled a building with retaining walls joined along the column and beams, , the retaining walls are just up to the ground floor, upon isolating a section of the grid having the retaining walls and the columns and beams, i can see the axial load FX shows that it increases from top of column till where the column meets the retaining wall, then the column below shows low axial force than one above it, will this give me an accurate result if i do footing for the column bases, because robot will take the lower value of the axial load in the column, I have attached a view of the axial loads presentation, is it okay that way or there's a way I'm to model such parts so that i get the real expected axial load value at the bottom column, thanks in advance
