Angle Bending Stress

[haynewp]

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.

 

[Taro]

The ASD manual contains a separate specification for single angle members (LRFD does also). Check the table of contents.

 

[legner]

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.
