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

• A. Joist Hanger
• B. Ledger plate
• C. Angle bracket
• D. Splice plate

Answer: (A)

When an I-joist and a beam meet, using a joist hanger is the recommended connection because it is specifically designed to support the ends of I-joists, ensuring that the load is efficiently transferred from the joist to the beam. Joist hangers provide a strong mechanical connection that helps prevent the joist from twisting or moving, which is essential in maintaining the structural integrity of a building. Joist hangers are typically metal brackets that secure the joist in place and facilitate proper spacing and alignment between framing members. This not only enhances load-bearing capacity but also reduces the risk of potential failure at the connection point. While ledger plates, angle brackets, and splice plates can serve different purposes in the construction process, they are not optimal for connecting I-joists to beams. Ledger plates are often used in deck construction but don’t provide the necessary support for I-joists. Angle brackets can provide some level of connection but may lack the load capacity required for this scenario. Splice plates are primarily used for joining two lengths of material together and are not intended for supporting a vertical load imparted by joists. Thus, the most suitable and effective option for connecting I-joists to beams is the joist hanger.
