ACI 8.6.4
ACI 8.6.4
(OP)
"It shall be permitted to analyze solid or ribbed
slabs built integrally with supports, with clear spans
not more than 10 ft, as continuous slabs on knife edge
supports with spans equal to the clear spans of the
slab and width of beams otherwise neglected."
What is the reason that spans longer than 10' are not allowed to be analyzed using a pin-support? How do you design one ways slabs with spans of 12' or more supported on beams?

If I use a knife edge (based on center of support) and design my interior beams for compatibility torsion, then why couldn't I take the moments based on a pinned model and take it at the center of the support?
It appears that I am missing something, but otherwise am I not conservative in my calculations?

I would never do this, however. It would throw off your reactions, which you need for beam design.

The comment states that this is not an appropriate method and I was curious what the intent of the code really is in this regard?
