Precast Hollow Core Plank Floors - Collectors

[RFreund]

If you have a precast plank floor or roof and it is either untopped or non-structural topping. What detail could be used for collectors/drag struts within the floor diaphragm?

Thanks!

Leave a gap and pour a column section between the planks.

Steel straps on the underside perhaps. It's not a great system in that respect in my opinion.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Both good ideas, thanks.
