Two Steel Plates
Two Steel Plates
(OP)
I know this should be be a problem that has been addressed before...but I've looked at numerous books and posts and can't seem to find a solution.
I have and opening to be covered by 1-inch thick roadplates. But a single 1-inch plate will be overstressed. We could lay two 1-inch thick plates over the trench but how do I calculate the capacity of the two plates? I know the two 1-inch plates have less capacity than one 2-inch thick plate.

Everyone else has covered it, but for what it's worth......... two members over top of each other but not acting compositely is identical to the two members side by side sharing the load instead of one member. Think of it as doubling b instead of h in the (bh^2)/6 for S
