@JAE, if the buckling mode is weak axis flexural buckling, i think you are completely right about adding horizontal batten plates, they plates need to resist shear...
Hello Everyone,
I just have a general regarding LTB for a coupled double channel:
If two simply supported channels are spaced quite far apart, say >=5", and they are connected only using vertical stiffeners/diagram elements at every X ft o.c.
1) Is the unbraced length for LTB the entire...
Hello Everyone,
I have a general question regarding how SAP2000 handles linear buckling.
In the buckling load case, there are two stiffness you can use, namely
(1) Zero Initial Conditions (Stiffness of Undeformed Structure)
(2) Stiffness after end of an load case, which can be analyzed using...
