Composite Slab Moment of Inertia 1

[bjkminn]

Has anyone seen a decking manufacturer's published list of slab / deck moments of inertia? I need to calculate deflections for various deck types and slab thicknesses and it would be nice to see this published.

See the "Composite Deck Design Handbook" published by SDI (Mar, 1997, Heagler et al.). No. CDD2

It has the data you are looking for.

If you have something not in a catalog, then just compute it manually using basic mechanics. Transform the deck to cocnrete or transform the concrete to steel and compute the transformed MOI.
