I'm going back to a question I've asked previously but the previous thread was closed.
I have a post-tensioned slab on grade that's 4.5" thick, supported by polystyrene underneath. See attached drawings.
It's a cold storage facility and I'm trying to establish how to calculate or justify the...
Thank you for the replies, and sorry for not responding earlier!
@kostast88: Thank you. I haven't confirmed where the water table is, are you thinking effect from buoyancy or deterioration? It's an old product and I don't have the product sheet. How would you check it? Cut a piece and take to a...
Hi everyone,
I'm working on the assessment of a big warehouse that used to be used for cold storage. From the old drawings, the slab construction is a 4-1/2" thick prestressed slab on 6" polystyrene. I know this warehouse was used for heavy storage and traffic. We're looking at placing heavy...
KootK, thank you very much for the suggestions! I tried a finer mesh and the diagram now looks closer to what I expected (see below). Etabs by default only assigns one shell element for one rectangular wall, and that works fine for planar walls, but when we have 3D walls, it looks like a finer...
Hi guys,
I'm modelling a simple single storey shear wall with load at the floor level. When I have a model with just a planar wall, the pier moment is zero at the top and maximum at the bottom, which is what I expected. However, when I add perpendicular flange walls and analyse with the same...
