Unbraced Length Determination at Connection 1

[Quade999]

Hi Everyone,

If I have a connection at a gusset plate as shown below, where the entire connection is welded, would the unbraced length of the bottom member be Unbraced Length 1 or 2? I would assume the connection would help prevent some out of plane buckling.

Thanks

Depends on what happens at the ends of the member. If the ends are braced, the welded connection provides a brace for in-plane buckling but not for out of plane buckling.

1 for buckling out of page. (Assuming ends of member are pinned).
