## beam with uniform loading supported at 4 corners

Hi
I have a wood beam (that has a width w , and a length L ) supported at 4 corners. A uniform load of wt lb/ft covers the entire top surface area of the beam. each corner has a structural tubing steel. when performing stress and loading analysis, how can I simplyfy the above to be a beam supported at two ends? is there any example or toturials that covers beams supported at 4 corners and the stress and loading analysis explained. ****this is not a homwwork problem ***
thanks

I'm not sure what you mean by 4 corners. Is the beam 'sandwiched' at each end in between 2 steel tubes at the top and bottom faces of the beam, or is this a very wide beam (flat plate, like a sheet of plywood) that sits on 2 tubes at each end, on the near and far corners of each edge?
 Recognitions: Science Advisor My understanding is that there are 4 cylindrical beams supporting the plate at all four corners. If so, then I really think you'll need to do some FEM on it, there will not be an accurate closed-form solution to this. Depending on the geometry, there will be stress concentration factors at the supports, and it would be difficult to model it as something simpler.
