angle bending stress
what method should be used to determine the allowable bending stress of an angle (of varying unbraced lengths)? chapter f of asd doesn't explicitly say angles and it would seem not very conservative to interchange these bending formulas, as bending of a plate about its strong axis would probably buckle easily.
the asd manual contains a separate specification for single angle   
the single-angle spec. starts on page 5-309 of the 9th edition asd. have fun! (stick to equal-leg angles for your own sake...)
also see the commentary section immediately following which begins on page 5-315.
seven references are included at the end of the commentary section which, together with the commentary, can further help in understanding the principles that go into the aisc specification.
