Two-Way Concrete Slab Supported by Steel Beams

[yxc]

I am currently designing a two-way slab supported by steel beams and/or walls, which is only continuous in one direction. The CSA code provides a method for designing rectangular two-way slab systems with stiff supports on four sides, but the criteria for determining whether a support is 'stiff' is for concrete beams, not steel. Any suggestions on how I can relate these concrete beam stiffness requirements to steel beams to be able to use this simplified design method?

Two way slabs develop a lot of strength from the torsion of fairly stiff edge beams. This is missing with structural steel.

YOu can model the system as knife edge supports using FEM with unbalanced loads or using yield line methods and then design the steel accordingly. You should be able to use a rational approach, but check with the AHJ...

Why not design it as a one way slab?
