Flat Plate design
Flat Plate design
(OP)
I am currently working on a analysis of an aluminum structure that consistes of verical and horizontal aluminum tubes. & 1/8" thk. aluminum plates with 3/4" sq. holes at 1" c/c that are fastened to these tubes to create a screen wall. The structure is specified to resist a 100 lb point load distributed over a 1 sq. ft area per the elevator code. This is a elevator screen wall. The structure must meet a maximum deflection of 1" under this loading condition. I do not have access to finite elemnent analysis software. Is there any way to analize this otherwise? I was think of using Roark's equations but one of the stipulations is that the plate must be of uniform thickness. Since the plate has holes in it I am not sure how or if the equations can be modified.

i don't think you'll see a deflection of 1" (for a 100 lb load) ... build a test. where are the reaction points ?

roark says about 14" (obviously unrealistic) for 0.06" thick.
i'd suggest building it, and planning on reinforcing it (with similar Al tubes as you're using on the edges), quartering the original panel. maybe leave out a row of holes (so it might look as though you knew what you were doing ??)

i used roark's solution of a concentrated load (a load distributed over a small area).
what if the point load is applied to the centre of one of the holes ?? ?)
