What type of connection should be used when an I-joist and a beam meet?

• A. Joist hanger
• B. Metal hurricane clips
• C. Metal framing ties
• D. Railing Tie

Answer: (A)

When an I-joist meets a beam, use a purpose-built joist hanger. This connector is designed to receive the end of the I-joist and fasten it securely to the supporting beam, transferring the load straight down and preventing rotation or shifting. Joist hangers are manufactured to fit I-joist flanges and depths, and they come with the appropriate fasteners specified for this connection, ensuring proper bearing and alignment. The other options aren’t correct for this application. Hurricane clips are intended to resist wind uplift at roof connections, not to transfer flooring loads where an I-joist sits on a beam. Metal framing ties are general connectors used in wall framing or other assemblies and don’t provide the secure, load-transfer connection required between an I-joist and a beam. Railing ties are for railing systems and have no role in floor framing connections.
