Steel beam web infill with wood

[JStructsteel]

Contractor wants to do face hangers on infill inside the steel beam. Do you folks think a detail showing the wood bearing on the flange is required, otherwise the cross grain capacity isnt that good. I have some longer spans, and also some beams framing into the sides. At beam hangers, would possibly need to have web stiffeners too.

I've used the detail lots of times, and it works without stiffeners. Bolts could be staggered at 2' o/c, ie. 2' between top and bottom bolts. Spacing may be close enough to cause shrinkage cracking in the infill lumber. Also any joists framing into the blocking should be 1/2 or more above the top of the steel beam. The joists may shrink and steel beam may be prominent on your floor plan.

Thanks Dik. I was thinking web stiffeners to brace the flange actually at beams that are heavily loaded.
