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

When an I-joist and a beam meet, the use of a joist hanger is the most appropriate choice for the connection. A joist hanger is specifically designed to support the ends of floor joists, including I-joists, by providing a secure attachment to the beam, which ensures proper load transfer between both structural components. This connection is critical for maintaining the structural integrity of the framing system.

Joist hangers are usually made of metal, offering enhanced strength and durability compared to other methods. They allow for precise positioning of the I-joist, ensuring it is level and aligned correctly with the beam. This precision is essential in achieving proper load distribution and minimizing any potential deflection or movement that could compromise the overall stability of the structure.

While other options like wood connectors, metal straps, and glue may have their applications in different contexts within construction, they do not provide the same level of structural support and ease of installation specifically at the junction of an I-joist and beam. In particular, wood connectors might not adequately support the loads involved in this situation, metal straps can be less effective for such connections, and glue alone lacks the immediate load-bearing capacity needed at this critical juncture.
