Hollowcore plank max point load
Hollowcore plank max point load
(OP)

How can I find the maximum allowable point load for hollow core plank load applied with a through bolt similar to the image attached? Assuming 8" thick 5,000 PSI slab, 10 ft long span.
The hollow core plank manual ( http://www.gateprecast.com/assets/files/PCI%20Holl... ) has a shear example on page 31 and 32 but it uses a PLF masonry load example.
Any help would be appreciated!






RE: Hollowcore plank max point load
Then after you calculate these capacities and calc the allowable point load capacity, check your local effects/actions of the through-bolt, based upon the proposed plate washers, bolt dia etc.
Doubt you will find a cookie-cutter solution for this, so back to basics.

How heavy are your heavy point loads?

If so, they may have some information and guidance, but as mentioned previously, this may be a pipe dream.

Thanks for the help. The point load 10,000 lbs on one bolt.
I called the manufacturer still waiting to hear back...

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.

You would have make the top plate large enough and thick enough to transfer the load to the 2 "webs" rather than rely on the concrete to carry the load.
