How should web stiffeners be installed where an I joist bears on an interior load bearing partition?

With a 1/4" gap at the top chord and tight to the bottom chordith a 14" gap at both chords.
Tightly between top and bottom chord.
With a 1/4" gap at the top chord and tight to the bottom chord.
Tight to the top chord with a 1/4" gap at the bottom chord.

The correct answer is: With a 1/4" gap at the top chord and tight to the bottom chordith a 14" gap at both chords.

The correct approach for installing web stiffeners in situations where an I-joist bears on an interior load-bearing partition involves maintaining a specific gap configuration to allow for movement and avoid issues related to shrinkage or expansion of the materials. Installing the web stiffeners with a 1/4" gap at the top chord and tight to the bottom chord provides necessary clearance that accommodates any vertical movement that may occur over time due to load changes or the natural settling of the structure. This method ensures that the stiffness is effectively added to the I-joist while also allowing for the flexibility needed to prevent buckling or other structural integrity issues. Additionally, having a 1/4" gap allows for proper adjustment and can help prevent potential damage to the I-joist or stiffener due to stress concentrations at the connection points. It's important to note that different installation practices could lead to complications, such as limiting the proper functioning of the joists or causing localized stresses that may lead to failure over time. The adoption of this strategic gap helps create a more robust and resilient framing system overall.
