Panel Bears on Bottom Flange of Steel Beam

Roof or floor panel bears on the bottom flange of the steel beam. Positive attachment is made with partially-threaded screws.

Purpose: Transfer of vertical loads from roof or floor panel to steel beam. Can also transfer shear along the length of the beam.

Design Notes

Capacity of primary load path is controlled by perpendicular-to-grain bearing capacity of floor panel or bending capacity of flange.
Increased bearing capacity requires wider or thicker flange.
Screws provide load path for in-plane loads.
Connection should accommodate different expected tolerance between steel construction and timber construction.
Consider eccentricity of load on steel beam if panel occurs on one side.
Constructability may depend on connection at opposite end of panel.
In panel design, consider that panel is not continuous across connection and multi-span conditions may not be achievable.
