Beam Bears on Steel Bearing Seat with Side Plates (Bucket)

Wood beam is connected to wood girder with a custom-fabricated steel connection consisting of a bearing plate and steel side plates (bucket) with dowel-type fasteners into girder. Beam bears on seat and is connected to side plate with dowel-type fasteners.

Purpose: Transfer of vertical load from wood beam to wood girder.

Design Notes

  • The capacity of connection is dependent on the screws, lags, and/or bolts in shear and perpendicular-to-grain bearing at the seat.
  • Face-mount connection is shown; top-mount connection is possible.
  • The capacity of this connection can be increased by installing screws into girder at an inclined angle.
  • At dowel connection, designer should account for shrinkage of beam with appropriate dowel location and spacing. See APA EWS T300 Glulam Connection Details Construction Guide for additional information.
  • Deck not shown for clarity. Beam may require bracing for lateral-torsional buckling.
