MDF & Plywood Shelving - Stress Analysis

MDF & Plywood Shelving - Stress Analysis

(OP)
Hello, I was wondering if someone here could help me out.

I'm looking to analyze MDF and plywood shelving spanning the load beams in our warehouse racking.  I can calculate the simply supported case (two edges supported).  However, I was wondering if someone can advise me how to calculate a scenario of 4 sides being supported (i.e. cross braces added between the load beams).  Basically, I need to figure out what interval we need to place these cross braces at.  

If anyone has information on the E modulus, poisson ratio, etc. of both MDF and plywood I'd appreciate if you could post it here.

Thanks in advance.
