Webthe shelving (failure is prevented by limiting bending and shear stresses) but for aesthetics and perhaps serviceability. For example, excessive deflection of a bookshelf may prevent removal of books from the shelf below. Most industrial shelving designers nominate Span/180 as the desired maximum initial deflection. However, surveys WebAssuming A 36 steel and using AISC LRFD Design procedures: Z x required = M max factored / 0.9 F y = 1.2 x 10,307/0.9 (36,000) = 0.424 in 3. Since Z x = bt 2 /6 = and the effective length of the angle is 16 inches, a minimum thickness of angle should be 0.424 = 16 x t 2 /6 = 0.399 inches.
