bending strength of rectangular bar
 

bending strength of rectangular bar
a client of mine has asked me to look at a stair railing with a rather unusual design. in trying to break it down into simple parts, i need to check the bending strength of a 3/8" x 1 1/2" rectangular bar about it's strong axis.
aisc 13th ed., section f11.1 covers yielding for rectangular bars with lb*d/t^2 <= 0.08e/fy, but is silent for bars with ratios greater than 0.08e/fy. of course, that is the case i'm up against.
i've already checked the ltb component of this problem, and i'm fine. i think i'm going to be fine for yielding, but the issue with the code concerns me.
thanks

check out our whitepaper library.
check aisc code f11-2, it has equations for slenderness ratios greater that 0.08e/fy. ltb will control if that is the case. if slenderness is less than 0.08e/fy than yielding controls.
thank you, ash060. that's what i thought, but just got a bit worried when i didn't see that explicitly spelled out.
