Truss connections are connections at the panel points of a planar truss, and are designed as tension/compression connections. In this video I discuss the specifics of trusses with HSS, including joint types, fabrication costs, failure modes, design approaches, welding, and more.

As a key takeaway, some of the top things to think about when designing trusses with HSS are as follows:

• Keep the number of different sizes small
• Try to minimize number of connections
• Understand effects of joint configuration and connection design criteria before analyzing truss and selecting member sizes

If you’d like more information on truss connections, the following are resources that I would recommend:

• AISC 360—Chapter K (2005 & 2010)
• AISC Design Guide #24
• CISC Desgin Gude 1997
• CIDECT Design Guides (available for free on AISC website)
