I am designing a 12" deep precast slabs that span over a creek at a residence to resist HS20-44. (2-10ft wide, 20ft span, 2" composite topping) I have designed it for flexural capacity and shear, and it meets the deflection and crack criteria. How do I specify the transverse steel? Is there a minimum required by ACI 318-99? The only examples I can find are for transverse slab design when you have stems supporting the slab, and this is not a stemmed member. Or is stripping and handling the only case I need to design for in the transverse direction?
