I 250156 3 12 10250 3 12 13110 6 mm 4 δ t 17442 3 320500013110 6 5110 -6 mmN. But what I dont necessarily agree with is designing the plate to resist bending without considering the contribution of the flange. Nutte Structural 25 Jan 12 1135. It is advisable to design the connection between such stiffeners and the flange to resist the tensile force due to the change of direction of the flange plate ignoring the bearing reaction. There may also be horizontal loading to consider from the bracing which may generate bending moments in the stiffener section. I found an example somewhat similar to this in Blodgett on page 33-25 and 33-26.
