Allowable material used for composite member
Allowable material used for composite member
(OP)
Engineers,
I am trying to determine stiffener size for a steel hopper for lignite. How much of the plate can I count on to help me carry the moment. I have found everything from 40 x thickness of the plate to 16 x thickness of the plate. I am using 1/2" plate and wide flange stiffeners. I have attached a sketch to try to clarify.

RE: Allowable material used for composite member
The Lincoln Arc Welding Foundation has a pretty good book on this general topic: “Tubular Steel Structures, Theory and Design,” by M.S. Troitsky. Several of the Structural Engineering Handbooks and Texts cover the general topic. For effective width and shear lag, take a look at some of the good Strength of Materials and Theory of Elasticity text books.
