Slabs
Slabs
(OP)
Greetings. In ACI, Design of one way slabs need only bars parallel to the short span to support positive (center) and negative moments (beam support) of the slab. Is there any advantage by framing bars perpendicular to it or parallel to the long side (grid) in one way slab design? I'm aware that if long side is 2 times or more than short side. The load in the short side or span is only 1/16 that of the long side. This is why normally bars are not used. But would anyone happen to design slabs with grid bars even if it is one way (perhaps for more stability)?

I have a condition where I need more steel in one direction than the other. But because of the relatively small slab size, I just gave the tighter spacing in both directions because I didn't want to confuse the drafters or the construction crews.
