How to calculate point load on suspended slab
(OP)
Does anybody know of an equation for calculating a point load (not line load) on a suspended 1-way slab? Treating the point load as a line load is way to conservative.

What are you trying to calculate?

moment from the point load?
Please try to explain what it is you would like to determine.

yeah moment and shear. the typical stuff

Is this a solid slab formed with plywood or is it a slab on metal deck or a precast slab or some other type? These will act differently under concentrated loads.
Are there several concentrated loads such as wheels from a fork truck? These will most likely have overlapping stresses.

I'm just asking a general question and am not working on any particular design.
RE: How to calculate point load on suspended slab
One word of caution: if you have two concentrated loads, the effective width needs to be reduced. I would suggest that the effective width be 0.3xL plus half the distance between loads.
I hope this helps!

Look at the link which apsix referenced above. The equations are in a contribution by "dbuzz". Note that if your load is near the edge, you should use an effective width equal to half the value plus the distance to the free edge.
