I’ve been asked to look at an angle that is made up of two plates [each 1.25”x20”] welded together. For the purposes of calculating allowable stresses, I am checking it by the 13th edition (of AISC). One thing that concerns me though: is this code even applicable? You look at the largest angle in the manual and it’s about an 8”.
So [to start off with] you check localized buckling by the values in Table B4.1 and it exceeds the compact limit but not the noncompact limit....but you wonder: is this applicable? Is there some other buckling mode outside the scope of this manual that may control? Thoughts?
