AISC Manual (14th Ed) - Chapter F13

AISC Manual (14th Ed) - Chapter F13

AISC Manual (14th Ed) - Chapter F13

(OP)
hey guys. anyone have any experience with Chapter F13 of the steel manual? i've never used it nor heard of it and just came across it.

if anyone had just some general thoughts on it or even design examples, that'd be jolly. thanks in advance

RE: AISC Manual (14th Ed) - Chapter F13

Most of us have dealt with F13. Do yo have a specific question about it that we can respond to?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

just in general what it's about. i tried reading it but i know those with experience here would be better at summarizing it. it seems to involve reductions due to holes in flanges i assume? any examples of how i'd use this in design/practice?

i.e., if someone asked me about F11, i'd explain that it describes how to design bars and rounds for flexure. i'm not really sure what F13 is about. thanks again in advance.

RE: AISC Manual (14th Ed) - Chapter F13

Sure, F13 deals with miscellaneous concerns that may affect the capacity of some flexural members.

F13.1 addresses our assumption that the tension flange of a flexural member will yield (and usually after we've reached a limit state on the compression flange, especially for doubly symmetric members). This is usually true, however for tension flanges with lots of holes, tensile rupture may be the governing failure mode, just like if your flexural member was really a truss with a tension chord.

F13.2 provides some general proportions for flexural members that makes sure the analysis methods and limit states prescribed elsewhere in Chapter F are applicable.

F13.3 provides guidance for beams with cover plates, specifically about the required development of those plates (the difference between physical length and theoretical length).

F13.4 Talks about the need to consider the connection between two beams which are joined and assumed to act compositely. (This section is unfortunately worded, IMO)

F13.5 discusses a modification to the unbraced length of a beam if you're taking advantage of moment redistribution per B3.7.

thanks a bunch!
