Concentrated wheel loads on steel checker plate
Concentrated wheel loads on steel checker plate
(OP)
Anyone know of an industry standard for designing steel "checker" plate for large concentrated wheel loads such as imposed by hard rubber tire fork lifts? AISC gives load tables for uniform distributed loads only. What trib width of plate should be assumed to carry the load?






RE: Concentrated wheel loads on steel checker plate
"The effective width of a slab which will participate in carrying the load can be obtained as follows. The effective width is the smallest of b1+5h, b1+4/3*x1, or b1+2/3*ln. If the load is at the edge of the slab use b1 plus 1/2 the additional width given above."
ln = clear span of slab between beams
b1 = width of patch load perpendicular to span
x1 = distance from edge of patch load to nearest supporting beam
h = thickness of slab
AISC 9th edition has design information for floor plate on page 2-145. You may also review previous post on concentrated loads on slabs.

I don't have much to add except that I use the Roark's Table 26 Case 1c for this type of calculation also. Just thought I'd stop in to second aggmans's post.

It is based on plate theory and boundary conditions at all four edges.
Good luck
