AISC Chevron Brace Example
AISC Chevron Brace Example
(OP)
Folks,
I have a question regarding the bracing connection example (Example II.C-5 HSS Chevron Brace Connection) in the AISC Design Examples V14. I have having difficulty getting my head around the calculation of the interface forces for Section b-b and the forces at point B. Maybe I am missing something very basic.
The design examples can be freely downloaded from here

It’s no trick to get the answers when you have all the data. The trick is to get the answers when you only have half the data and half that is wrong and you don’t know which half - LORD KELVIN

However, I don't understand the calculations of M1' and M2'. It is something very basic that is tripping me.

Not using a consistent sign obliges following the signs, that gives some trouble, but I think that is the explanation. Respect the restriction for the orthogonal to the chord components being equal is not much when the connection is calculated hinged.

(Va/2)x(L/4)
so no dirty thinking on Ma=2V1 etc, confusing mixed notations. Everything in the B formula just related to the A point (weld interface).
Tomorrow I will post the refined answer. Sorry for the temporary confusion.
(was not already in the mood of sleeping, it seems).
Best wishes

Can you post (or send privately) AISC's response? Did they indicate the procedure that was going to be used when they revise that problem? If we wait for the next design example to be published (whch probably won't happen until the next specification gets approved) then we will probably be waiting a long time!
