Joist framing into a girder is acceptable if supported by?

Joist framing into a girder must be adequately supported to ensure the structural integrity and safety of the building. The requirement for support is fulfilled by using either an approved framing anchor or a properly sized ledger strip, which should be no less than a 2 inch by 2 inch nominal size. This larger size provides sufficient surface area for the joists to rest against the girder, distributing the load effectively and reducing the risk of failure.

Using an approved framing anchor would allow for secure connections that help resist lateral and vertical forces, contributing to the overall stability of the structure. The emphasis on using a designated size for ledger strips ensures that the support is robust enough to handle typical loads without compromising the joist integrity, making this option a key requirement in framing practices.

In contrast, smaller strips or insufficient fastening methods, such as just one nail or a minimally sized ledger strip, may not offer the necessary support and safety required in construction practices. Therefore, it's essential for builders to adhere to established guidelines for proper framing connections.
