Integrity Steel in Two Way Slabs
Integrity Steel in Two Way Slabs
(OP)
I am currently working on the design of a two way slab. I have been using spSlab (Structure Point) for this. I am currently reviewing the design output for integrity steel at the columns and the numbers are very high. I discovered that the program is including the service loads from the steel columns above (directly over the podium columns) in the loading used to calculate the amount of integrity steel required.
My understanding of integrity steel was that it is meant to take the punching shear force from the slab. IN CSA A23.3 we have "Vse = shear transmitted to the column or column capital due to specified loads, but not less than the shear corresponding to to twice the self-weight of the slab." Does this imply the service loads from the column above should be included?
Thanks,
MF

I believe the 2Vse is intended to (roughly) represent the dead load of the tributary slab area, but somebody can correct me about that if I'm wrong.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

@KootK, there is a place to include column loads and displacements so that you can simply take the column load output data and move on to use it as input in spColumn.
Thanks again,
