How much weight can sawhorses hold with a distributed load on I-beams?

[blake92]

In this type of setup, i was wondering what i needed to take into account to determine how much weight each sawhorse can hold. when an evenly distributed and uniform load is applied ontop of the I-beams.

Do i need to determine the max load of the I-beams going across?

How will the I-beams affect my answers?

Do i need to determine the forces in the saw horse legs?

These question and related material that you think is crucial is what I am trying to find out. Thanks for your help!

I just want to know where all the forces are going and if i applied let's say 100lbs to the I-beams evenly would each take on half of that (50lbs) and then would each saw horse take half of that (25lbs) per beam?
