Panel Bears on Steel Beam with Angles
Roof or floor panel bears on steel angles fastened to web of steel beam, typically with welds or bolts. Positive attachment between angles and panel is made with partially-threaded screws.
Purpose: Transfer of vertical load from roof or floor panel to steel beam. Can also transfer shear along the length of the beam.
- Capacity of primary load path is controlled by perpendicular-to-grain bearing capacity of floor panel.
- Connection should accommodate different expected tolerance between steel construction and timber construction.
- Horizontal leg of angle sized to accommodate screw installation and panel bearing area.
- Screws provide load path for in-plane loads.
- Consider eccentricity of load on steel beam if panel occurs on one side.
- Constructability may depend on connection at opposite end of panel.
- Steel beam depth to be great enough for screw installation.
- In panel design, consider that panel is not continuous across connection and multi-span conditions may not be achievable.
