HSS Brace to HSS Column
HSS Brace to HSS Column
(OP)
Greetings,
I have a question regarding connecting an hss brace to an hss column, virtually all connections I have seen in books, AISC, online.. etc... connect the hss brace to the hss column by means of a gusset plate, I understand the way this connection works.. however I wonder why the connection cannot be made by directly welding the brace to the column as if it was a truss.. and using the K chapter specs of the AISC. Is there a particular reason why this is not commonly done?... I ask because using a gusset plate on a hss wall comes with its own problems as the connection strength will always be limited by bending of the column wall... similar when using X-braces there is always some complicated plate detail when joining the braces at the X.. is not easier to just have one continuous brace and the other welded as a truss cross connection?
Thanks.

Welding on the rounded edge?
Overhand welds? In tight spaces.
Think it through, remember it needs to be constructable and fast and lowest net cost. Time is money.

Constructibility is the number one thing engineers overlook in design. It should be the one of the first considerations in the design process, not an after thought.
The gusset provides the flexibility required to reduce the risk of putting unwanted moments into members. Rigidly welding a brace to a column creates a fixed-end brace and any bending will put unplanned moment into column.
