Plate Supported on Four Sides

Plate Supported on Four Sides

Plate Supported on Four Sides

(OP)
Does anyone have a design chart or table for a rectangular plate continuously supported on 4 sides, fixed and/or simple to accommodate a point load on the plate at stipulated dimensions from the support (not necessarily at mid point)?

Sounds like an easy job using Yield Line Analysis.

FEA ???

RE: Plate Supported on Four Sides

Roark would be my choice here...

I didn't find anything like that in Roark's. Only uniform type loads.

JAE:

You might be able to approximate it with Table 26, Case 1b on page 386.

If all the edges are fixed instead of pinned, then Case 8b on page 393 could be used.

this should be easy on any fea program.

RE: Plate Supported on Four Sides

7th Ed, pg 502 ... (pg509 for fixed)
table 11.4 (rectangular plates),
case 1 (all sides SS),
load b (pressure applied to a small area) ... ahh, but since this doesn't refer to the location of the load you'd assume it's central ... ref21 = our friend Timoshenko "Plates and Shells"

Quando Omni Flunkus Moritati

RE: Plate Supported on Four Sides

I assume the OP is looking for large pl deflection and not small pl deflection...big difference...the following is a ref I have used in the past besides Roark..
"Thin Plate Design For transverse Loading" By B. Aalami....John Wiley & Sons...probably out of priny by now..
