You could eliminate the cantilevers altogether and simply use a large slab edge overhang. You'll get designs that way, though they could be unconservative.

Hey Seth!

Thank you for your prompt response. I have already tried the case you mentioned. But, like you have called out caution, that joist will now belong to a SP design case, I did encounter the "xxGSP" design. I would like to know how I can design the joists without specifying the depth.

Model short beams (of any material) between the tips of the cantilevers. Then model the slab edge out-board of those perimeter beams, Be aware that cantilevers on joists will also cause a special (SP) design case. See this for more: communities.bentley.com/.../ram-steel-joists-faq
