Point load on plate with continuous edge support
Point load on plate with continuous edge support
(OP)
Brain doesn't seem to be working this morning.
Just need point in the right direction really.
Large point load on the bottom flange of a Channel. Just need to make sure it doesn't yield. Don't have any finite element packages available to use at the moment.
Where should I be looking for guidance here?
In Australia btw.

PFC itself is continuously restrained against torsion, so its essentially just a point load bending the bottom flange down.
Just not with it at all today it seems.
Trying to find something good on yield line analysis, can imagine that would suit.

Any good literature on Yield Line Analysis?
There are a few design guides from the Australian steel institute that are great, and reference it, but nothing on it really.

Any decent one out there for Yield Line Analysis in general? Unfortunately it isn't something that is taught at University here, and I'm yet to come across the need for it in what I've been doing.
Ever learning!

The method used in the reference cited by Hokie93 does not take into account the fact that the web of a channel is thinner than the flange. It should therefor not be used for your case.
At the risk of repeating myself, why don't you turn the channel around and attach an angle to the back of the channel to form a track?

At this stage I can't change their design, merely trying to certify.
If a angle was used, the same calculation needs to be made on the point load on a 'flange', so I still need to figure that out correctly.
Its a 300PFC, with a 66kN point load. I did a quick check to see what width of flange would be required, and got around 300mm. From this I don't think it is sufficient. But will try figure this yeild line analysis out.
