Panel Bears on Beam at Notch

Design Notes

Capacity of primary load path is controlled by perpendicular-to-grain bearing capacity of floor panel or notch.
Reasonable minimum notch bearing width is 1″.
Shop machined notch provides more reliable elevation control than applied bracket or ledger.
In panel design, consider that panel is not continuous across connection and multi-span conditions may not be achievable.
Beam must be designed for reduced net section.
Bearing on a notched glulam introduces tension perpendicular to grain. Review NDS sections 3.8.2, 11.1.3, and Commentary section C12.5. For perpendicular to grain connections, the member is required to be checked for shear in accordance with 3.4.3.3 and 5.3.10 using the reduced depth.
The mid-span notches in the girders as shown are outside the scope of notches permitted in the NDS and should only be used after careful consideration and justification through alternative means.
