I'm designing a U shaped bucket bracket that supports a glulam beam and is bolted to the bottom of an I beam so the glulam beam will be hung from the I-beam. My question is in regards to the forces in the bracket itself, primarily in the base plate that the glulam beam bears on. I'm modeling to bracket as 1" strip with a uniform load along the base plate,see attached image. If I cut the model at along the center to analyze the forces at the base plate, there is a moment in the base plate which would require a very thick plate to resist the moment. I'm assuming my assumptions on how the load would be distributed through the bracket is incorrect however I can't seem to see what's wrong. Similar per-manufactured brackets with similar loads are using 3 gauge steel, does the stiffness of the beam not distribute the load to the base of the bracket in such a way to induce the moment?
